In this episode, Rupert speaks with Sanskritist and scholar-practitioner of Classical Tantra, Dr Christopher Wallis. They discuss the understanding that is at the heart of some of the greatest spiritual traditions, such as Christianity, Sufism, Advaita Vedanta, and Kashmir Shaivism, and how Advaita and Tantra, even though they emphasise different aspects of the understanding, are complementary and contained within each other. 

They also talk about the importance of translation, how the truth needs to be reformulated by each generation, and how the self that is said to be void, or empty, from the point of view of the finite mind is, in fact, plenitude itself.
