Jagat Singh (1884–1951) was an Indian Surat Shabd Yoga practitioner and initiate of the Sant and Radha Soami Satsang Beas Guru Sawan Singh. He worked as a college chemistry professor at an Agricultural College[1] and was honoured for meritorious service by the British as Sardar Bahadur. After retirement he was chosen by his spiritual master to be his successor, becoming the third spiritual head of Radha Soami Satsang Beas. Remembered as quiet, inconspicuous, and unassuming, he was once described by the Muslim mystic Sain Lasoori Shah of Lyallpur as a "perfect disciple" who became a "perfect Master".[2][3]
