Sri Yukteswar was born on May 10, 1855, to a wealthy businessman and his wife in Serampore, India. He was given the name Priya Nath Karar.
He met Babaji, the guru of Lahiri Mahasaya, in 1894. Babaji told him that one day he would send Sri Yukteswar a disciple who would share the teachings of yoga in the West. This disciple turned out to be Paramhansa Yogananda, who is best known for his book, Autobiography of a Yogi. Babaji also asked Sri Yukteswar to write a book on the essential unity of the Bible and Bhagavad Gita, the most well-known scripture in India. Sri Yukteswar titled this book The Holy Science.
