Sri M, also known as Sri Madhukarnath, is an Indian yogi, spiritual guide, social reformer and educationist. He was born on 6 November 1949 in United State of Travancore–Cochin (now in Kerala). He currently lives in Madanapalle, Andhra Pradesh, India.

Sri M left his home at age nineteen to find his master in the Himalayas. Exhausted by the search, he met Sri Maheshwarnath Babaji—the same person he had met when he was nine—at the Vyasa Gufa (cave) near Badrinath. He lived with Maheshwarnath Babaji for three-and-a-half years and learned many things. Initiated into the Nath tradition, his Kundalini energy was awakened.

He always desired to meet Grand Master Sri Guru Babaji (Mahavatar Babaji) was fulfilled on Nilkantha Hill with the help of Maheshwarnath Babaji. He claimed that Sri Babaji was his master in a previous life, and Maheshwarnath Babaji reportedly had the power to materialize and de-materialize in any form on earth or beyond.

He also heads the Satsang Foundation, which runs two schools in Andhra Pradesh: the Peepal Grove School and the Satsang Vidyalaya. The Peepal Grove School, a boarding school, was inaugurated by former President of India A. P. J. Abdul Kalam in 2006. Satsang Vidyalaya is a free school for children in the Madanapalle area, where he lives. The foundation began Bharat Yoga Vidya Kendra, a training programme for yoga teachers, in 2020. He writes in “Speaking Tree”, a spiritual forum run by The Times of India. A documentary film, The Modern Mystic: Sri M of Madnapalle, was directed by Raja Choudhury in 2011.

Sri M is an initiate of the Nath tradition of Hinduism and is the disciple of Sri Maheshwarnath Babaji, who was a disciple of Sri Guru Babaji (Mahavatar Babaji). He received the Padma Bhushan, India’s third-highest civilian award, in 2020.
