DATU, BABA (1537-1628), son of Guru Angad and Mata Khivi, was born in 1537 at Khadur Sahib in present day Amritsar district of the Punjab. Like his elder brother, Dasu, he too was not reconciled to Guru Amar Das succeeding his father as Guru. But whereas Dasu had soon realized his error and acknowledged Guru Amar Das as true inheritor of Guru Nanak`s spiritual legacy, Datu remained hostile. He took to yogic practices to attain supernatural powers and thereby to create a following of his own.
