Geographical Aspects in Rigveda (ऋग्वेदोक्त भौगोलिकविषयाः)

The Rgveda is treated as the storehouse of recorded valuable geographical information. It contains references to places, rivers, mountains, forests and oceans. To put it in a nutshell, more or less pertains to the area in the northern belt from Uttar Pradesh and Bihar in the east to Afghanistan in the west, the easternmost river mentioned in the text being the Ganga, and the westernmost being the western tributaries of the Indus rivers.

Mountains

The mountains mentioned in the Rigveda (ऋग्वेदे पर्वतानां विवेचनम्) give us a good insight on the geographical aspects of ancient mountain ranges that exist in the present times. One interesting point of mention is about Moojavat mountain, which is said to be the native habitat of Somalata used in Somayajnas.

Oceans

Rgveda offers good information about oceans, seas and other water bodies such as streams. People were well aware about the vast waterbodies and trade via the seas was prevalent. The terms samudra (समुद्रम्), udadhi (उदधि), sindhu (सिन्धु) and Arnava (अर्णव) have been used for ocean or a sea. In one context we find that the term 'sindhu' and samudra are mentioned together, in which sindhu means the river. We also find references to travel using boats or ships (Rgveda 1.25.7) for whom the direction is given by Varuna (by his winds). Some important findings include the following

• Thar Desert was once a sea (Rgveda 7.95.2): In the present day Rajasthan where we see a desert now, the ancient texts have indicated the presence of a sea in the same area.
• It is in these seas that treasure is said to be available, namely gems and precious stones (Rgveda 1.47.6, 7.6.7, 9.92.44 etc).
• People had knowledge about the origin of pearls (मुक्ताः) the semi-precious stone, from the seas (Rg.Veda. 1.47.6)

• That the huge waves in the seas are caused by the air circulation was mentioned in Rgveda (1.19.7 and 8, 1.119.4 etc). Other mantras describe that a hurricane can destroy the ships in the sea.
• Presence of natural gases in oceans is discussed in Rgveda (Rgveda 8.102.4) It is termed as पुरीष्य अग्निः। This is so called because it has the ability to light up and spreads across in various places of the ocean bed.
• Medicinal substances and food items from the oceans, rivers and mountains is well explained in this Veda (Rg. Veda. 8.20.25).

Bhujya Akhyayana

Ancient Indians were explorers; thus shipping, marine travels, and trade-routes were well established. Many mantras are mentioned as reference for the Rgvedic merchants who navigated the four seas in quest of wealth.

The anecdote of Bhujya, the son of Tugra, describes about the sea-voyages. According to this legend, Bhujya undertakes a long journey over the sea, using ships which are a hundred "dandas" (an ancient unit to measure length) long. As soon as the doubt that the ships might break and sink arises, Bhujya prays to the Ashvini devatas for protection. With their help he docks the ships to safety and praises the deities who protected his life. A few things are clear here, namely, that

• the Rigvedic people had clear knowledge of travelling on the seas and oceans
• they were well versed in constructing big ships of sizeable proportions
• they were adept in navigating these big ships on the high seas

चतुःसमुद्राः ॥ Four seas

It is known that the present peninsular Indian subcontinent is surrounded by three seas (Bay of Bengal, Indian Ocean and the Arabian sea in the present terms). In many mantras of Rgveda there is a mention about "two seas (उभी समुद्रौ)" namely the 'पूर्व (purva)' which refers to the Bay of Bengal and 'पर (para)' samudra refers to Arabian sea (Rigveda 10.136.5). It is important to note that Rgvedic texts mention about the presence of a fourth sea in the northern region of India below the Himalayas.

रायः समुद्राँश्चतुरोऽस्मभ्यं सोम विश्वत: । आ पवस्व सहस्रिण: ॥६॥ (Rg. Veda 9.33.6)

स्वायुधं स्ववसं सुनीथं । चतुःसमुद्रं धरुणं रयीणाम् ॥ (Rg. Veda. 10.47.2)

वात॒स्याश्वो॑ वा॒योः सखाथो॑ दे॒वेषि॑तो॒ मुनि॑: । उ॒भौ स॑मु॒द्रावा क्षे॑ति॒ यश्च॒ पूर्व॑ उ॒ताप॑रः ॥५॥ (Rg. Veda. 10.136.5)

The Muni referred to here is identified with Keshi or Sun whose rays are like the golden hairs of an ascetic. The Sun is also compared to a horse in the Rgveda. Keshi or Sun dwells both in the Eastern and Western seas, because he is seen to rise from the Eastern sea and sink down into the Western sea. Now this Eastern sea could be none other than the sea that washed the eastern shores of Sapta Sindhu. It is over this sea that the Ashvini devatas preceded and heralded the Dawn. Further it was from the depth of these waters that the Sun was seen, from the shores of Sapta Sindhu, to emerge and ascend the sky (Rg. Veda. 3.55.1). Of these four seas, the Rgveda mentions about two, the 'पूर्व (purva)' and 'अपर (apara)' samudras. The Purva (or अवर-Avara) samudra also called as Arvavat (अर्वावत्) is where the sunrises and the Apara (or पर - Para) samudra also called as Paraavat (परावत्) is where the sun sets. The Arabian sea is the Paraavat sea where the Sindhu and its tributaries drain into. It however, ran up the present lower valley of the Indus along the foot of the Western Range, and covered a large portion of the present province of Sindh. However, scholars opine that the Purva (Apara or Arvaavat) sea is not the same as the Bay of Bengal as this bay is very far from where the Saptasindhu rivers were flowing. It has been proposed that land areas that are now known to be Uttar Pradesh, Bihar, i.e., the gangetic plains were we find the rivers Ganga and Yamuna, were once areas of a sea (in the Pleistocene era) which got filled with the sands brought down by the rivers and became plains. Geological evidence goes on to show that there were actually three seas on the three sides of Sapta Sindhu, i.e., the Eastern, the Western and the Southern and the fourth sea logically must have been somewhere on the north beyond the Himalayas. There is a mention that a deep trough (sea) did exist at the foot of the Himalayan range in ancient geological times as per Mr. Wadia (in his Geology of India book). This trough or sea lasted through long ages during which it was gradually filled up with alluvium into which were embedded the remains of a rich varied fauna "of herbivores, carnivores, rodents and of primates, the highest order of the mammals," brought down by the rivers and streams.

ये अ॑स्या आ॒चर॑णेषु दध्रि॒रे स॑मु॒द्रे न श्र॑व॒स्यव॑: ॥३॥ (Rg. Veda. 1.48.3)

According to Dr. A. C. Das, geological evidence proves that such a sea did actually exist in ancient times, stretching from below the highlands of modern Turkestan towards Siberia on one side, and from the confines of Mongolia to the Black Sea, on the other, covering an immense area. This sea disappeared in comparatively recent geological times, leaving the Black Sea, the Sea of Aral, Lake Balkash, and an extensive depression low, dry and converted into steppes, as its remnants. The Black Sea was not at that time connected with the Mediterranean, and its western shores formed the Isthmus of Bosphorus linking Europe with Asia. On the confines of East Turkestan also there was in ancient times another immense Asiatic Mediterranean Sea, of which Lake Lobnor is the remnant. These stern geological facts are corroborated in Rgvedic mantras. We can see the effects of climate change reflected in the mantras and the disappearance of one of the four seas around the Sapta Sindhu, and the upheaval of a vast tract of arid desert in the South. Dr. Das's discussion about various geological evidences

"clearly proved the existence of the four seas mentioned in the Rgveda, round about the region, inhabited by the ancient Aryans, which included Sapta-sindhu on the south, Bactriana and Eastern Turkestan on the north, Gandhara on the west and the upper valleys of the Ganga and Yamuna on the east. The age of the Rgveda, therefore, must be as old as the existence of these four seas in ancient times."

It is time we delve deeper into the geological testimony which supports the vast antiquity of Rgveda stretching back to times immemorial.

Rivers

In these texts, we see There are at least nineteen rivers mentioned in the Rg veda, with the Sarasvati and Indus rivers (along with it's tributaries) gaining a lot of attention. The rivers mentioned in Rigveda (ऋग्वेदे नदीनां विवेचनम्) drew a great attention in the past few centuries with the Sarasvati (सरस्वती), though long lost, has occupied the media but generally for the wrong reasons. Dr. Michel Danino meticulously summed up the issues and debates associated with Sarasvati backed with the latest research and archeological evidences.
