The Indian approach to human life and the Universe is for me more of a philosophy than a religion. They called Vedanta since it is the studies of the Vedas scriptures, books written in verses, poetry usually called Sutras that were channeled by the ancient mystics of India, the Richies. They were transmitted in the form of poetry and chants generations after generations from the teachers to the disciples. They were the origin and substratum of a vast religion: Sanatana Dharma known popularly as Hinduism. And they are also part of an incredible compiled knowledge of many different sciences in India, medicine, mathematics, astrology, etc.
The Indian Cosmology is expressed in the Sutras (Sacred Verses) that comprehend the science of Ayurveda. It is a science of truth as it is expressed in life; it encompasses science, religion and philosophy.
