‘Sapta- Sindu’ the Homeland of the Rigvedic Culture – Literary Evidence

Prof. Shashi Tiwari, General Secretary, WAVES-India 

There are so many questions related to Vedic people under discussion as part of Indian history, religion, mythology and civilization. The hunt for their original land has been a particularly important topic of research among Indologists and historians since Sir William Jones’s pronouncement in 1786, in Calcutta, that ‘Sanskrit, Greek, Latin, Celtic and old Persian were related languages with common source.” The whole of nineteenth century was dedicated to the study of language and literature of Vedic and ancient Sanskrit texts, where the study of dates, editions and interpretations was done. The publication of two volume of Vedic Index by A.A. Macdonell and A.B. Keith in 1912 was almost the closing work in this field. Macdonell placed the Aryan entry into India at about 1500 BC. The establishment of the notion of a common Indo- European heritage, at the beginning of British rule in India, was a powerful instrument to rule Indians, so this view was highlighted in various ways. Ironically, in 1907 came archaeological evidence from Boghszkoi (east Turkey), which established the existence of the names of the Rgvedic  deities in fourteenth century BC.

In the 1920s, the ancient cities of Harappa and Mohenjodaro were discovered. Tentatively a time period of 2500 -1500 BC was assigned to these cities at that time. Since the estimated date for the end of these cities coincided with the estimated date for Aryan entry into India, it was emphasized that these cities were brought to an end by Aryan invaders. Aryan invasion was sometimes called as Aryan migration. In either case Harappans were declared as Non-Aryans. Now many historians and Sanskrit scholars are refuting these theories on the basis of various categories of evidence. They think that the Homeland of Aryans was Indian continent or Aryans themselves were Harappans.  It is understood generally that Harappan civilization began at about 3300 B.C. and takes its earliest roots at Mehrgarh. Excavation has shown that this civilization possessed a writing system, as well as a social and economic system.

In my understanding, the Vedic civilization is the earliest civilization in Indian history for which we have written records.  The vast Vedic literature provides important materials to understand every aspect of the Vedic people and their views. The mantras present an extraordinary picture of culture, religion, philosophy, economics, polity, ritualistic practices and scientific knowledge of the Vedic people. It looks like such an organized and developed society based on agriculture, arts and crafts, trade and industry, education; characterized by a deep interest in nature and environment, and moved by the spiritual urge. These facts have been proven in my earlier papers written on agriculture, economics, architecture, birds, animals, food, ornaments, weapons, society and education of the Vedic people.  In the entire Vedic literature, the authors of Vedas never say a single word about their migration or invasion. Rather they indicate their stable and calm establishment in numerous places in the literature.

Evidence from within the Vedas suggests that the Vedic people were acquainted with the seven rivers, especially with the mighty river Saraswati. The description of mighty Sarasvatī  and references related to the terms Sapta-sindhavah͎ and Sapta-Sindhuṣu in Rigveda show a rich historical tradition of Vedic people in that area. The country of seven rivers is very dear to them. Saraswati is described as sapta svara (having seven sisters- 6/61/10, 8/10/9). It is said to be the mother of seven rivers (saraswat̄i saptadhī sindhumātā. -7/36/6). There is much talk and exploration of the river. She is a great river rushing down from mountains towards the ocean (ekā acetat sarasvatī  nadīnām shuchir yāti giribhya ā samudrāt -7/95/2). She is far superior to her companions (uttarā sakhibhyah -7/95/4). She surpasses all other streams by her sheer majesty (prabābadhanā rathyeva yāti  -7/95/1) and glory (pra yā mahimna mahināsu cekite -6/61/13). She is the best of rivers, best of mothers and best of goddesses (ambitame, nadītame devitame sarasvati -2/41/16).

The core region between Sarasvati and Drisadvati rivers was called vara aprithivya (the earth’s best place) and nabha prithivya (the navel of the earth).  It also has been known as ‘Kurukshetra’ (the land of the Kuru people). Manusmriti called it ‘Brahmavarta’ (the divine land). According to mantras, Vedic people feel affection for this area because their civilization began and flourished there in the Saraswati basin since 5000 to 4000 BC. This was the homeland of Vedic Aryan people. Broadly it was the sapta sindu region where Sarasvati was Main River. According to two mantras there were three sets of seven rivers (i.e. twenty one rivers)- trih͎ sapta sasrā nadyo mahir (10/64/9) and pra sapta sapta tredh̄a hi  (10/75/1). The Vajasaneyi-samhitā  (34.11) talks about of five rivers joining the Sarasvati. So we see that the descriptions vary slightly due to the symbolic poetry of Vedic Seers. The important point though, is their fascination regarding the sapta-sindhu area and the river Sarasvati.  The Aitareya and Shatapatha Brahamanas repeatedly mention that Sarasvati either got fanned out in deserts or dried up. Later on, the drying up of Sarasvati led to migrations of people towards the northwest or westward of the Sarasvati river system .This is the opinion of many scholars today.

Atharvaveda’s Bhumi sukta depicts the picture of Indian land. It has six seasons (12/1/36 ), colorful soil, sea, rivers,  mountains, and glorious description of ancestors. In the Rigveda we find names of only three seasons – vasant, grishma and sharad (RV 10/90/6) but they are indicative of winter and rain. These seasons are familiar to Northern India.


The principal food of the Ṛgvedic Aryans consisted of barley-flour and its various preparations, rice and other cereals, fruits, honey, clarified butter (ghee), curd and other preparations of milk. The sowing, ripening, and ploughing of Yava is mentioned in the Ṛgvedic verses. Etymologically, barley was called Yava because its grain, though one, has two distinctly marked parts, which are still not separated. Specimens of barley, unearthed from the ruins of Mohenjodaron shows its use in that region even in the Ṛgvedic age. It is certain that barley and some other grains were cultivated in Ṛgvedic times. Barley was offered to gods. In their prayers, Vedic people are found asking gods for this grain. In the Atharvaveda it is called one of the two immortal sons of heaven, i.e. barley and rice (AV.8/7/20). These two were the staple crops that were cultivated by the Ṛgvedic Āryans, one in winter or spring and the other during the rainy season. It may be that, as the climate of Punjab was extremely cold in the Ṛgvedic times, the cultivation of barley was more convenient and yielded bumper crops rather than that of rice. Moreover ‘Vrīhi’ – meaning rice – is frequently referred to in the later Vedic works. Dhānya, Dhānā are other words denoting grains in general. It is but natural that for agriculture and cultivation a stable society and lifestyle is needed. Thus seasons, grains and agriculture prove the homeland of Aryans as the region of seven rivers near Punjab.

It is important to note that Salt (Lavan͎a) is not mentioned in the Rigveda, but is frequently mentioned later. Keith and Macdonell has observed that, “it is somewhat surprising, if the regions then occupied by the Indians were the Punjab and the Indus valley, where salt abounds, (that it is not mentioned) it is however, quite possible that a necessary commodity might happen to be passed over without literary mention in a region, where it is very common”. It is sure Āryans knew it because in a Ṛgvedic mantra they talk about thirst (Trishn͎ā) between waters of ocean ( RV 7/89/4).

We found description of ornaments and jewellery in Ṛgveda, almost similar to what we found in Harappan excavations. In both descriptions people used them to decorate head, ears, neck, finger, chest, hands, waist and legs, These decorative items were made of metal,  mud or stone; such as  man͎i grīva, nis͎ka, khādi,sraj, rukma, hiranyavartani etcGenerally it is said that Rigvedic people were living in mud houses in villages. We found that houses and building materials were not unknown to them. In one Mantra worshipper says to Varuna that ‘he does not want to live in a house made of clay’.- Mo shu varuna mrinmayam griham rajan naham gamam (7/89/10). Instead he askes to Parjanya Deva to give ‘tridhatu Sharnam (7/101/2 ) i.e. ‘three  storied dwelling’ according to H H Wilson and ‘Tribhumika house’ according to Sayana. Ayasi Puh (7/95/1) i.e. ‘Fort of iron’ is used for metaphor. Ishttikas meaning bricks are described variously in Brahamana texts. Dvara for door, and chardi for terrace are in common use in the Rigveda. Two ‘Shaala’ sukas  in Atharvaveda describe about bigger and systematic house. This shows that Vedic people liked clean and strong houses for living. Study of Ṛgvedic birds, animals and plants are also relevant in this context to decide about the place and period of Vedic culture. Undoubtedly these too indicate their Indian origin.

Vedic civilization, as reflected in the Ṛgveda, is seen developing gradually in all aspects in the later Vedic texts. Keeping in mind the scientific principles of development of any civilization, it would be appropriate to think of the early period of Vedic civilization as 5000 to 4000 BC. Its later period may be assigned during Harappan period.  Further, other categories of evidence, incorporated with literary evidences, may provide advanced chronological findings of our ancient times.





Scientific Significance of OM

              – Dr. Raj Kumar, Assistant Professor, Institute of Advanced Sciences, Dartmouth, MA.

IMG_5362Dr. Kumar has developed a broad multidisciplinary background in analytical chemistry, biochemistry, spectroscopy, biophysical studies, cell culture, cell and animal assays. He is an alumni of Banaras Hindu University, Varanasi where he completed his bachelor and master in science. He completed his Ph.D. from University of Massachusetts, USA, in the field related to Botulinum Neurotoxin. Before joining to the institute, he worked as a lecturer in UMASS, Dartmouth. Apart from his own field, he has also developed the interest in studying the various aspects of Vedas. He already published an article about Ayurveda. As a rational thinker, he emphasized more on scientific aspects of Vedas.

From the very words of the Krishna Yajurveda, Kapisthala-katha-Samhita (42.1) —–Prajāpatir vai idam āsīt: In the beginning was Brahman. Tasya vāg dvitīya āsīt; with whom was the Vāk (or Sound)… Vāg vai paramam Brahma; and the Vāk (Sound) is Brahman”. According to the “Shabda Yoga”—– The Science of Light and Sound, creation came into being through the light and sound of the creator. This sound is called OM. There is no scientific evidence which can provide proofs whether OM is a sound of creation or not. Although all the spiritual thoughts/aspects/truth cannot be verified with modern scientific tools, a few fundamental bases can be tested with modern scientific instrumentation (may not be appropriate all the time). In this blog, my efforts will be more concentrated on the scientific basis rather than the spiritual one.

First look into the phonetics of the word. According to Mandukya Upanishad (Johnston, 1923), OM is the manifestation of all states of time, Atman, consciousness, and knowledge. In Sanskrit, the sound “O” is a diphthong spelled “AU”.  A diphthong is a mixture of two vowel sounds and can be separately heard. This is why OM sounds “AUM”, which represents the 3-folds division of time.

A (apti) represents the waking state (symbolizes darkness, inertia, ignorance).

U (utkarsha) represents the dream or creative state (symbolizes passion, activity, dynamism).

M (miti) represents the state of deep sleep or meditative state (symbolizes purity, truth, light).

When we sleep we dream and this dream state is part of bigger dream state which we experience in waking state. The dream which we see in the meditative or sleeping state is the dream within dreams, and the life is a big dream or illusion. At the end of OM chanting, there is complete silence.  This represents the state of Turiya, the fourth state; infinite or pure consciousness. Achieving this state evaporates all dreams and one faces the reality (dream disappears and truth emerges). Chanting of OM symbolizes a journey of darkness to pure light—–

The symbol of OM is also representation of these four states (Johnston, 1923). The large bottom curve symbolizes the waking state, A. The middle curve signifies the dream state, U. The upper curve denotes the state of deep sleep, M. The dot signifies the fourth state of consciousness, Turiya. The semi-circle at the top represents “Maya” and separates the dot from the other three states. The illusion of Maya due to the materialistic world is an obstacle to the realization of the pure consciousness (Fig. 1).

Figure 1Figure 1: A representation of word OM.

Now, examine the significance of the above explanation scientifically. Heisnam Jina Devi and colleagues analyzed sound related to OM (A, U, M and AUM). They observed that A is flat, U is initially flat but finally tapered off or flattened off abruptly, and M is the synchronized sound of U which gradually tapered or flattened off. Thus, OM sound is a mixture of all three sounds (A, U, and M) (Fig. 2).

In another experiment, scientists analyzed fMRI before and after OM (Kalyani et al., 2011). Chanting of OM affects the vibration and generate resonances near to the ear, very close to the cranial nerves. These resonances are transmitted through the auricular branch of the vagus nerve. Chanting of OM has significant deactivation of amygdala, parahippocampal and hippocampal brain regions.

Chanting of OM mantra sequentially activates the stomach, spinal cord, throat, nasal and brain region. The energy moves from stomach all the way to the brain. Resonance observed in fMRI in the vagus nerve supports the above point. So, chanting OM has several benefits – therapeutic, physiological and spiritual.

Om is also called Pranava, meaning it sustains life and runs through the breath or Prana. The ‘O” or ‘AU’ sound makes all the bones of the thoracic cage vibrate, which leads to the vibration of lungs and finally to the delicate membranes of the alveolus. This can stimulate pulmonary cells and enables a proper exchange of air in the lungs.  These vibrations produce a much accentuated effects in the endocrine glands. This leads to the balance activation of several glands and organs. Besides this vibrational message, which results from the emission of the vowels ‘AU’, the latter acts especially in the abdominal and thoracic cage, whilst the vibration of ‘M’ in the skulls induces a vibration of the cranial nerves. Gurjar and Ladhake (2008) concluded, based on their research, that OM chanting steadys the mind, which ultimately helps in reducing stress of the human mind.

Based on the above data OM can be represented as a model (Fig. 3), summarizing the above arguments as follows. By chanting ‘A’ we activate communication of body and mind, whereas chanting ‘U’ and ‘M’ activates conscious and unconscious mind which finally connects to infinite or pure consciousness.

Figure 3(1)Figure 3: A model representing different components of OM.

In my view, there are two important components which are the basis of Vedic philosophy: a) The unmanifest (avyakt) gives rise to the manifest (vyakt), and b) Sound vibration is a tool which provides a medium for this transformation. The primordial sound is a medium (pure consciousness) from where everything emerged and to which everything will return. Thus, sound vibration has a profound effect on the physical, conscious/unconscious, astral, and spiritual body. This is one of the reasons why Vedic philosophy considers OM as a primordial sound.
