There have been several renaissance movements in Hinduism which have reformed and revitalised it. One of the latest of such movements is the one started by Guru Nānak (A. D. 1469—1538). It is now known as Sikhism and considered as an independent religion.
Guru Gobind Singh (A. D. 1666—1708) formed the Khālsā (lit., ‘personification of the guru’) an army of baptised Sikhs. The process of baptism consisted of stirring water in an iron bowl with a double-edged sword, mixing it with sugar and drinking it, as also sprinkling it on the face. Sacred verses from the Guru Granth Sāhib were uttered during the stirring. The water itself was called ‘amṛt’ or nectar. The procedure is followed even now.
