The Indian Knowledge System (IKS) is a collection of knowledge and practices that have developed in India over thousands of years. It includes many areas such as philosophy, mathematics, medicine (like Ayurveda), arts, architecture, farming, and understanding nature. This traditional wisdom was passed down through generations and has helped people live in harmony with nature and society. Today, in the 21st century, there is a growing interest in bringing this ancient knowledge together with modern science and technology. By combining the old with the new, we can create better and more sustainable ways to live. For example, using traditional farming methods along with modern tools can protect the environment and produce healthy food. Similarly, using Ayurveda along with modern healthcare can improve overall well-being. This paper explores how Indian Knowledge Systems are being brought back into use and how they are being blended with today’s scientific innovations. It also looks at what this combination means for areas like education, health, environment, and sustainable development. Finally, it explains why this mix of traditional and modern knowledge is important and useful in today’s world.
