Guru Nanak (Sikhism) (apr 15, 1469 – sep 22, 1539)

Description:

the founder of Sikhism, was born in the village of Rāi Bhōi dī Talwandī, now called Nankana Sahib (in present-day Pakistan).[173] His parents were Punjabi Khatri Hindus.[174][175] According to the hagiography Puratan Janamsakhi composed more than two centuries after his death and probably based on oral tradition,[176] Nanak as a boy was fascinated by religion and spiritual matters, spending time with wandering ascetics and holy men.[177] His friend was Mardana, a Muslim. Together they would sing devotional songs all night in front of the public, and bathe in the river in the morning. One day, at the usual bath, Nanak went missing and his family feared he had drowned. Three days later he returned home, and declared: "There is no Hindu, there is no Muslim" ("nā kōi hindū nā kōi musalmān"). Thereafter, Nanak started preaching his ideas that form the tenets of Sikhism.
