Pramukh Swami Maharaj (born Shantilal Patel) (7 December 1921 – 13 August 2016) was the guru and Pramukh, or president, of the BAPS Swaminarayan Sanstha, an international Hindu socio-spiritual organization. BAPS regards him as the fifth spiritual successor of Swaminarayan, following Gunatitanand Swami, Bhagatji Maharaj, Shastriji Maharaj, and Yogiji Maharaj. He was believed by his followers to be in constant communion with Swaminarayan, and ontologically, the manifestation of Akshar, the eternal abode of Swaminarayan.Pramukh Swami Maharaj received initiation as a Hindu Swami in 1940 from Shastriji Maharaj, the founder of BAPS, who later appointed him as President of BAPS in 1950. Yogiji Maharaj declared Pramukh Swami Maharaj to be his spiritual successor and guru of BAPS, a role he commenced in 1971.
As president of BAPS, Pramukh Swami Maharaj had overseen the growth of BAPS from an organization centered in Gujarat, India, to one spread around the world, maintaining many Hindu Mandirs and centers outside of India. He built more than 1,100 Hindu temples, including the Swaminarayan Akshardham temples in New Delhi and Gandhinagar, Gujarat.He had also spearheaded the efforts of BAPS Charities, which is the charitable service organization affiliated with BAPS. Pramukh Swami Maharaj is succeeded as the guru and President of the BAPS Swaminarayan Sanstha by Mahant Swami Maharaj.
Shantilal was born in the village of Chansad, Gujarat, on 7 December 1921. His parents, Motibhai and Diwaliben Patel, were disciples of Shastriji Maharaj and followers of the Akshar Purushottam faith.Motibhai and Diwaliben were both involved in the Swaminarayan fellowship; Diwaliben’s family’s association with the Swaminarayan fellowship extended to the time of Bhagatji Maharaj.Shastriji Maharaj had blessed young Shantilal at birth, and had told his father, “This child is ours; when the time is ripe, please give him to us. He will lead thousands to the devotion of God. Through him, thousands will attain liberation.”
Shantilal’s mother described him as a calm and soft-spoken, yet energetic and active child.His childhood friends recall that Shantilal developed a reputation in the town and in school as an honest, reliable, mature, and kindhearted boy.Even as a child, he possessed an uncommon empathy that led others to seek out and trust his opinions and judgments in matters large and small.Shantilal was raised in a simple home environment, as his family was of modest means. Although he excelled in his studies, in the seventeen years he spent at home before becoming a sadhu, Shantilal only had the opportunity to attend school for six years.As he grew older, Shantilal helped his household by doing chores on the family farm.
