Budista-Hinduista : Baba Sri Chand (8 September 1494 – 13 January 1629), was the founder of the ascetic sect of Udasi and was the elder son of Guru Nanak, first Guru and founder of Sikhism. He was born to Mata Sulakhani on Bhadra sudi 9, 1551 Bikrami (i.e. 8 September 1494)
ਪੁਤ੍ਰੀ ਕਉਲੁ ਨ ਪਾਲਿਓ ਕਰਿ ਪੀਰਹੁ ਕੰਨ੍ਹ੍ਹ ਮੁਰਟੀਐ॥
His sons did not obey His Word; they turned their backs on Him as Guru.
ਦਿਲਿ ਖੋਟੈ ਆਕੀ ਫਿਰਨ੍ਹ੍ਹਿ ਬੰਨ੍ਹ੍ਹਿ ਭਾਰੁ ਉਚਾਇਨ੍ਹ੍ਹਿ ਛਟੀਐ॥
These evil-hearted ones became rebellious; they carry loads of sin on their backs
Some organizations, like Gobind Sadan, Damdami Taksal, a few Nihangs, and even a few Jathedars of takhat, admire Sri Chand Ji for his contribution. Sri Chand Ji is said to have composed an Aarta – a poem in name of his father, Nanak.
After having differences with many subsequent Sikh gurus, Guru Angad, Guru Amar Das Guru Ram Das and Guru Arjan, however there was reconciliation between Sri Chand and sixth Sikh Guru Guru Hargobind. He died at Kiratpur on 13 January 1629. [Wikipedia]
