The sutra teachings are common to all Buddhist traditions and form the basis for all the teachings that came later. The insight into emptiness and nonsubstantiality is the essential platform from which the tantric and nondual teachings arise.

There are several Indian Advaitic texts that are hidden jewels; The Ribhu Gita is one of them. It forms the sixth section of a larger Sanskrit work known as Shiva Rahasya. These are the teachings on nonduality given by Shiva to Sage Ribhu, who passed them on to his disciple, Nidagha.

Spiritual texts that have stood the test of time continually reveal the truths they embody through the hearts and minds of those who apply their teachings in daily life. The fact that a teaching lives this way allows it to endure.
