Vidya Gita (Song of Knowledge) in simple English rhyme is from the Tripura Rahasya. Herein The teacher is Sri Tripura Sundari and diciples are the legendary sages who were inquiring into the Knowledge of Awareness, bliss and Non-dual Brahman-Consciousness.
Gita and Ramayana are perhaps the sum total of the fabrics of Hinduism (a way of life).
The Gita (song) are teaching by Divine or ancient revered holy rishis teaching both metaphysics and practice of disciplined action. They proclaims that life is worth living, teaches how it should be lived and the path to self-realisation. They are the cream of the Upanishads, which themselves are the core of the Four Vedas.
