The echoes of ancient Indian wisdom can be heard from the oldest of scriptures that existed many years ago. Even thousands of years before they were written down on palm leaves, the teachings were passed on from generations to generations, from the teachers to the disciples in their oral form. These works are amongst the oldest of humanity. They laid the foundation of one of the most tolerant and diverse religions in the world, the Sanatan Dharma or Hinduism, which is marked by a wide range of ethos and philosophical approaches.
