Guru Ram Das Ji (Punjabi: ਸ੍ਰੀ ਗੁਰੂ ਰਾਮ ਦਾਸ ਜੀ [ɡʊru ɾɑm dɑs]; 1534–1581) was the fourth of the Ten Gurus of Sikhism and was given the title of Sikh Guru on 30 August 1574.

Ram Das was born in Chuna Mandi Lahore, Punjab on 9 October 1534[1] to a Sodhi family of the Khatri clan. His father was Hari Das and his mother Anup Devi. His wife was Bibi Bhani, the younger daughter of Guru Amar Das. They had three sons: Prithi Chand, Mahadev and Guru Arjun Dev Ji.

His father-in-law, Guru Amar Das, was third of the Ten Gurus. Amar Das installed Ram Das as the fourth guru on 1st September 1574.

As a Guru, one of his main contributions to Sikhism was organizing the structure of Sikh society. Additionally, he was the author of Laava, the four hymns of the Sikh Marriage Rites. He was planner and creator of the township of Ramdaspur which became the Sikh holy city of Amritsar. He founded it in 1574 on land he bought for 700 rupees from the owners of the village of Tung. Earlier Guru Ram Das had begun building Santokhsar Sarovar, near the village of Sultanwind in 1564 (according to one source in 1570). It could not be completed before 1588. In 1574, Guru Ram Das built his residence and moved to the new place. At that time, it was known as Guru Da Chakk. (Later, it came to be known as Chakk Ram Das). In Amritsar, he designed the gurdwara (ਗੁਰਦੁਆਰਾ) Harmandir Sahib (ਹਰਿਮੰਦਰ ਸਾਹਿਬ), which translates as "The Abode of God" also known as the Golden Temple.

Snatam Kaur Khalsa (Punjabi: ਸਨਾਤਮ ਕੌਰ ਖਾਲਸਾ, born 1972 in Trinidad, Colorado), is an American singer and songwriter. She lives in Santa Cruz, California. Kaur performs Indian devotional music, kirtan, and tours the world as a peace activist. The name "Kaur", meaning "princess", is shared by all female Sikhs.

Her family moved to California when Snatam was two, living in Long Beach and Sacramento. When Snatam was six, the family went to India where her mother studied kirtan. Snatam lived on a ranch near Bolinas, California until 8th grade and then moved to Mill Valley in 1986. During her childhood, she played kirtan with her mother in Sikh temples and at Sikh religious ceremonies. She attended Tamalpais High School in Mill Valley. While at Tam High, she played violin in the school orchestra and began songwriting. Bob Weir of the Grateful Dead coached Kaur and her classmates before they performed her song Saving the Earth at an Earth Day concert in San Francisco on April 22, 1990.^{[citation needed]}

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.
