Sri M, also known as Sri Madhukarnath Ji, is a highly respected Indian spiritual figure who is recognized as a yogi, social reformer, and educationist. He belongs to the Nath sub-tradition of Hinduism and is a disciple of Sri Maheshwarnath Babaji, who was himself a disciple of Mahavatar Babaji. Sri M has made significant contributions to Indian society through his work in education and social reform.

Currently residing in Madanapalle, Andhra Pradesh, Sri M has been honored with India's prestigious Padma Bhushan award in 2020, which is the third-highest civilian award given by the Indian government. He is highly regarded for his spiritual teachings and is seen as a leading authority in the field of yoga and meditation. His followers include people from all walks of life, including political leaders, celebrities, and everyday citizens seeking guidance on their spiritual journeys.

Sri M, born Mumtaz Ali Khan in 1949 in Trivandrum, Kerala, is a spiritual guide, social reformer, and educationist. He was born into an affluent Muslim family and had a life-changing experience when he was just nine years old. He met his guru, Maheshwarnath Babaji, in the garden of his home in Trivandrum. The youthful-looking stranger with matted hair stood near a jackfruit tree and disappeared after a brief conversation with Sri M. This meeting was a turning point in his life, and he started meditating without even knowing the word meditation. Sri M went on to meet several South Indian saints, including Bhagawan Nityananda of Ganeshpuri, Yogi Gopala Saami, Kaladi Mastan, Swami Abhedananda, Chempazhanti Swami, Swami Tapasyananda, and Mai Ma. At the age of nineteen, he left his home in search of his master in the Himalayas. After an exhausting search, he met Sri Maheshwarnath Babaji again at the Vyasa Gufa (cave) near Badrinath. He lived with his master for three and a half years and was initiated into the Nath tradition, and his Kundalini energy was awakened. Sri M's desire to meet Grand Master Mahavatar Babaji was fulfilled on Nilkantha Hill with the help of Maheshwarnath. Sri M claimed that Mahavatar Babaji was his master in a previous life, and Maheshwarnath reportedly had the power to materialize and de-materialize in any form on earth or beyond. After spending three years in the Himalayas as a wandering yogi with his master, Sri M returned to his normal life at the behest of his master. He traveled throughout India, meeting gurus such as Neem Karoli Baba, Lakshman Joo, and J. Krishnamurti. Sri M spent a substantial amount of time in the Ramakrishna Mission and the Krishnamurti Foundation. He met his future wife, Sunanda Sanadi, while associated with the foundation, and they have two adult children.

 Sri M 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 Sri M lives. The foundation began Bharat Yoga Vidya Kendra, a training program for yoga teachers, in 2020. Sri M also writes for "Speaking Tree," a spiritual forum run by The Times of India. In 2011, a documentary film, "The Modern Mystic: Sri M of Madnapalle," was directed by Raja Choudhury. In 2015, Sri M undertook a "Walk of Hope": a 7,500-kilometer (4,700 mi) padayatra from Kanyakumari to Kashmir. The walk began on 12 January, the birth anniversary of Swami Vivekananda, who had undertaken a similar journey over a century earlier. With a group of fellow travelers, Sri M walked through 11 Indian states, considering the Walk of Hope an exercise to restore the country's spirituality. The padayatra ended in Srinagar, Kashmir, on 29 April 2016. Sri M published the second part of his autobiography, "The Journey Continues," in 2017. It details apparently-miraculous incidents that he experienced and to experience in his spiritual journey, as well as the challenges he has faced in spreading the message of peace and harmony. He emphasizes the need for interfaith dialogue and respect for diversity in India, and his efforts in this direction have been widely appreciated. Sri M continues to guide people on their
