Guru Nanak said that he had been taken to God's court. There, he was offered a cup filled with amrit (nectar) and given the command "This is the cup of the adoration of God's name. Drink it. I am with you. I bless you and raise you up. Whoever remembers you will enjoy my favour. Go, rejoice of my name and teach others to do so. I have bestowed the gift of my name upon you. Let this be your calling." From this point onwards, Nanak is described in accounts as a Guru, and Sikhism was born.
Guru Nanak travelled across the length and breadth of not only India, but also far beyond into Arabia, Mesopotamia (Iraq), Ceylon (Sri Lanka), Afghanistan, Turkey, Burma and Tibet.
He was the first of the ten Sikh Gurus. It is believed that the spirit of Guru Nanak's sanctity, divinity and religious authority descended upon each of the nine subsequent Gurus when the honour was bestowed upon them.
