The corpus Vedic constitutes the basis of the Indian Knowledge System (IKS), having a wide and heterogeneous array of fields, viz., philosophy, linguistics, astronomy, mathematics, and medicine. Being among the oldest bodies of human knowledge, the Vedas—viz., Rigveda, Yajurveda, Samaveda, and Atharvaveda—convey deeply spiritual as well as scientific perceptions. This article examines the multi-faceted contribution of the Vedic texts to the development of India's knowledge traditions, tracing their influences on Ayurveda, Jyotisha (astronomy), linguistics, and mathematical sciences. It also discusses the knowledge preservation methods, including the oral transmission practices that helped perpetuate Vedic knowledge. The research highlights the applicability of Vedic wisdom in modern scholastic and inter-disciplinary research, connecting ancient and new scientific thinking. Through the review of these inputs, this work seeks to confirm the importance of the Vedic corpus in designing intellectual traditions as well as establishing holistic paradigms for learning.
