Sufi-sampradaya
Sri Caitanya-caritamrta
CC Madhya-lila
CC Madhya 18.190, Purport: The revealed scripture of the Muslims is the Koran. There is one Muslim sampradāya known as the Sufis. The Sufis accept impersonalism, believing in the oneness of the living entity with the Absolute Truth. Their supreme slogan is “analahak.” The Sufi sampradāya was certainly derived from Śaṅkarācārya’s impersonalists.
