Abu Yazid al-Bestami (ca. 801-874)

Noted Islamic mystic who founded the ecstatic school of Sufism. Born in Bestam in northeastern Persia, he became known as al-Bestami. His claim that the mystic quest could result in complete absorption and identification with divinity is thought to have been an influence of Hindu Vedanta. In this respect, his heterodoxy was blasphemous to orthodox Islam.

Beginning with the Sufi concept of approaching divinity as the lover approaches the beloved, al-Bestami claimed that this love was in itself an obstacle. He renounced conventional worship in the mosque, pilgrimage to Mecca, and even the mystical practices of asceticism and meditation. Various miracles were ascribed to al-Bestami.
