[5] The famous Savaiya and Dohra from the Rehras Sahib, read daily by devout Sikhs, comes from Ram Avatar Bani.
[8] A common misconception associated by Hindus when looking at Sikhism is looking at Ram Chander, while for Sikhs it is derived from Gurmat (Guru's understanding/philosophy).Gurmat describes Rama as the omnipresent, all prevailing-lord.
You must make that distinction.Rama is mentioned as one among the 24 incarnations of Vishnu in the Chaubis Avtar, a composition in Dasam Granth traditionally and historically attributed to Guru Gobind Singh.
Others have discredited the statements of Rajinder Singh on the basis of the janam sakhis attached dating from 18th century and later, which is stated to be a time period when Brahminical revivalism became evident in such works.
Sikh scholars have the view that Guru Nanak went to religious sites like Mecca and Ayodhya to preach and spread his message rather than for pilgrimage.
