“Brahman is truth, knowledge, and infinity, hidden in the highest heaven.” This provides a philosophical foundation for Vedic cosmology.

This blog, written on June 2, 2024, as part of our weekly series on Vedic Science on HinduInfoPedia.org, delves into the fascinating realm of Vedic astronomy, exploring its enduring legacy and contemporary relevance.

Historical Context of Vedic Astronomy

The Vedic period, spanning from approximately 1500 to 500 BCE, was a time when astronomy in ancient times played a crucial role in both religious and daily life. The Vedas, particularly the Rigveda, contain numerous references to celestial bodies and their movements, reflecting the ancients’ deep engagement with the cosmos. These texts discuss the structure of the universe, creation theories, and the significance of celestial phenomena in Vedic rituals. For instance, the Rigveda’s hymns provide detailed accounts of the solar and lunar cycles, eclipses, and planetary motions, showcasing an advanced understanding of ancient astronomy.

The Nasadiya Sukta from the Rigveda delves into the mysteries of creation, pondering the existence of the cosmos before its formation:

नासदासीन्नो सदासीत्तदानीं नासीद्रजो नो व्योमा परो यत्।
किमावरीवः कुह कस्य शर्मन्नम्भः किमासीद्गहनं गभीरम्॥१॥

[Rigveda 10.129.1]

“There was neither non-existence nor existence then; there was neither the realm of space nor the sky which is beyond” (Rigveda 10.129.1).

Fundamental Astronomical Insights from Vedic Texts

Vedic cosmology is rich with astronomical knowledge, offering profound insights into the workings of the universe. The Vedas present a comprehensive view of cosmology, including theories on the creation and structure of the cosmos. Celestial bodies such as the sun, moon, and planets are frequently mentioned, emphasizing their importance in Vedic rituals and daily life. Specific hymns detail the lunar and solar cycles, providing accurate predictions of eclipses and other celestial events. This intricate knowledge reflects the advanced state of ancient science in India, where astronomy was deeply intertwined with religious and philosophical thought. The history of astronomy in India is deeply rooted in these texts, showcasing a sophisticated understanding of the cosmos.

The Rigveda describes the twelve-spoked wheel representing the year, emphasizing the eternal cycle of time:

द्वादशारं न रथं तस्थुषस्त इह सं वर्ष्ण उपयन्त्यश्वाः।
अथाह्नां प्रथमं जायमानं तदासत्सूर्यो जातवेदाः॥६॥

[Rigveda 1.164.6]

“The twelve-spoked wheel, revolving endlessly, never ages).

The Purusha Sukta presents Purusha as the cosmic being, whose body constitutes the universe:

सहस्रशीर्षा पुरुषः सहस्राक्षः सहस्रपात्।
स भूमिं विश्वतो वृत्वा अत्यतिष्ठद्दशाङ्गुलम्॥२॥

पुरुष एवेदं सर्वं यद्भूतं यच्च भव्यम्।
उतामृतत्वस्येशानः यदन्नेनातिरोहति॥३॥

एतावानस्य महिमा अतो ज्यायांश्च पूरुषः।
पादोऽस्य विश्वा भूता नि त्रिपादस्यामृतं दिवि॥४॥

[Rigveda 10.90.2-4]

“A thousand heads has Purusha, a thousand eyes, a thousand feet. He envelops the earth on all sides and stands beyond the width of ten fingers.”

We can further elaborate the above thus: The Purusha Sukta’s depiction of Purusha highlights the interconnectedness of the universe, where the cosmic being embodies all creation. This metaphor reflects the Vedic understanding of the universe as an integrated whole, with each part connected to and dependent on the others. It also illustrates the Vedic view of the cosmos as both a physical and a spiritual entity, where the material world and the divine are intertwined.

Influential Astronomers and Their Contributions

Several notable Vedic scholars made significant contributions to the field of Indian astronomy. Aryabhata, for example, developed an accurate calendar system and proposed theories on planetary motions and eclipses that were ahead of his time. Brahmagupta’s work further refined astronomical calculations and introduced innovative concepts in mathematics and astronomy. Varahamihira’s contributions included the compilation of comprehensive astronomical texts that integrated Vedic insights with contemporary knowledge. These astronomers not only advanced the understanding of the cosmos but also laid the groundwork for future developments in the history of astronomy in India.

Techniques and Tools of Vedic Astronomy

Ancient Indian astronomers employed various observational methods and tools to study the cosmos. Instruments such as gnomons, used to measure the angle of the sun’s shadow, and water clocks, which tracked time through the flow of water, were integral to their observations. These techniques allowed astronomers to measure time accurately, predict celestial events, and navigate effectively. The precision and ingenuity of these tools highlight the sophistication of Vedic vigyan and its practical applications in Indian astronomy.

The Atharvaveda speaks of the interconnected fabric of the universe, reflecting the holistic view of Vedic cosmology:

यस्मिन्निदं सर्वमोतं प्रोतं च बभूव यत्।
स नो विश्वस्य भेषजं सन्नमूलं मिमीतु नः॥३२॥

[Atharvaveda 10.8.32]

“In whom the entire universe is woven and interwoven, that all-pervading cosmic healer, may he lay out our foundation.”

This verse from the Atharvaveda underscores the Vedic view of the universe as an interconnected entity, where everything is interwoven. This holistic perspective aligns with modern scientific concepts of interconnected systems and reflects the ancient understanding of the cosmos as a unified whole.

वेदाहमेतं पुरुषं महान्तमादित्यवर्णं तमसः परस्तात्।
तमेव विदित्वातिमृत्युमेति नान्यः पन्था विद्यतेऽयनाय॥१॥

[Chandogya Upanishad 3.19.1]

“I have known that Great Being, effulgent like the sun beyond darkness. By knowing him, one transcends death; there is no other path for going there”.

The above sloka is explained thus: This verse from the Chandogya Upanishad highlights the Vedic understanding of the cosmos as not just a physical space but also a spiritual journey. The realization of the supreme being (Purusha) is seen as essential for transcending the material world and understanding the deeper truths of existence. This philosophical approach influenced later scientific thought by embedding a holistic view of the universe, integrating physical observations with spiritual insights.
