Cosmology (Brahmānda Vijñānam) and Astronomy (Jyotişam) in ancient Bharat were intricately linked, showcasing a unique fusion of scientific observation and spiritual insight. The sages perceived the cosmos as a vast interconnected system, reflected in Vedic texts like the Rgveda and Atharvaveda, which explore the universe's origins and cyclical nature. Ancient Bharatiya astronomers developed advanced mathematical techniques, as seen in texts like the Sürya Siddhānta and Aryabhatiya, demonstrating a sophisticated understanding of celestial phenomena, including the diurnal rotation of the Earth. Cosmological narratives, such as the concept of Mount Meru as the universe's centre, influenced sacred geometry and temple design, emphasizing the harmony between physical and spiritual realms. Instruments like the gnomon and observatories like Jantar Mantar advanced astronomical observations. The translations of Bharatiya texts into Arabic and Latin helped disseminate this knowledge, significantly impacting global astronomy and the renaissance. The holistic approach of ancient Bharatiya scholars offers profound insights into existence and the inter-connectedness of all things, reminding us of the civilization's remarkable wisdom and creativity.
