Swami Sri Yukteswar ji was the Guru of Paramhansa Yogananda. His given name was Priya Nath Karar. Upon leaving college, he married and had a daughter, and in 1884 he became a disciple of Lahiri Mahasaya. After the death of his wife, Priya Nath Karar became a Swami and received the name Sri Yukteswar Giri.
Sri Yukteswar ji founded two hermitages, one in Serampore near Kolkata, and one in Puri, Orissa. They formed the backdrop for Paramhansa Yogananda’s training and his many experiences narrated in the Autobiography of a Yogi.
