By his grace, the gate of liberation is found. So clear references to the Hindu notions of karma, that action drives consequences, that you enter one physical body after another. But that's not your true self, the robe of this physical body. There's a true self. And eventually, through the grace of the ultimate reality, you might be able to have liberation, have moksha. So clear Hindu parallels as well. One angle is that Guru Nanak and Sikhism was attempting a reformation of both, taking elements that were compelling in either and then purifying them, making them more internal focused, less focused on ritual, less focused on the external, and more focused on meditation and the true self.
