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.”

He claims that VHP is an international organization which speaks for Hindus. He also claims that the majority of the work concerning the emancipation of the lower castes is not done by Christian Missionaries but by Hindu organizations.

Singh Kaur (1955–1998) was a new age music composer, vocalist and instrumentalist, who had a prolific career that lasted from the early 1970s to the late 1990s, releasing 23 albums. With her angelic voice and haunting melodies, Singh Kaur was a pioneer in the growing genre of Western interpretations of Indian chanting music.

Singh Kaur initially lived at the Tucson ashram, and it was there she began to flower as a musician. Although she had arrived with 'St. Francis' already complete, she was exposed to the eclectic musicians of the 3HO community and a new, spiritually-focused, way of living. She later moved to the Espanola, New Mexico 3HO community, where her musical talents expanded and she found her footing as a composer and singer of inspiring devotional songs. It was at Espaniola that she met, and later married, Gurucharan Singh. Not long after their marriage, they moved to Denver to open a health food restaurant. From there, they moved to St. Louis for the purpose of opening a yoga ashram. During their years in St. Louis, Gurucharan and Singh Kaur had two children, Guru Shabd and Guru Ardas.
