Guru Nanak was a nice man, and he mixed hinduism and islam to avoid conflict between both parties. Its sad he failedf to see the truth in islam and used alot of quranic verses in some of his books, especially abt the sun and the moon being a sphere?
Some of his teachings are good. Like he taught hindoos to forsake teir silly superstitions, like in one story hindoos were pouring water in a field saying that it will reach the dead, Guru Nanak upon seeing this took some water and threw the other side n said to the hindoos that by throwing water here it will reach his padi fields.
But alot of his teachings are from the Quran.
