Jñāna yoga (Devanāgarī: ज्ञान योग; the pronunciation can be approximated by jnyaana yoga") or "path of knowledge" is one of the types of yoga mentioned in Hindu philosophies. Jñāna in Sanskrit means "knowledge".

As used in the Bhagavad Gita, the Advaita philosopher Adi Shankara gave primary importance to jñāna yoga as "knowledge of the absolute" (Brahman), while the Vishishtadvaita commentator Ramanuja regarded knowledge only as a condition of devotion.

Ram Dass (born Richard Alpert on April 6, 1931) is an American contemporary spiritual teacher and the author of the seminal 1971 book Be Here Now. He is known for his personal and professional associations with Timothy Leary at Harvard University in the early 1960s, for his travels to India and his relationship with the Hindu guru Neem Karoli Baba, and for founding the charitable organizations Seva Foundation and Hanuman Foundation. He continues to teach via his website.

Alpert was born to a Jewish family in Newton, Massachusetts. His father, George Alpert, was a lawyer in Boston, president of the New York, New Haven and Hartford Railroad, one of the founders of Brandeis University and the Albert Einstein College of Medicine, as well as a major fundraiser for Jewish causes. While Richard did have a bar mitzvah, he was "disappointed by its essential hollowness". He considered himself an atheist and did not profess any religion during his early life, describing himself as “inured to religion. I didn’t have one whiff of God until I took psychedelics.”
