He didn't. He didn't he didn't It can't and does not.....however, faith has a great placebo effect. God is in all of us, it is up to us to realise "God". Control and defeat the 5 thieves and realise what is already within you. I would suggest read about Sikhism from rational sources eg Dr Gopal Singh, Dr I J Singh, Patwant Singh etc. You seem to have got your information from Sakhi's which at best are unreliable, and at worst utter nonsense.
