Guru Nanak's Hindu and Muslim followers began to be called Sikhs (learners). He taught them to bow only before God, and to link themselves to the Guru, the Light of Truth, who lives always in direct consciousness of God, experiencing no separation. Through words and example, the Guru demonstrates to followers how to experience God within themselves, bringing them from darkness into light. Guru Nanak was a humble bearer of this Light of Truth. He opposed superstition, rituals, social inequality and injustice, renunciation and hypocrisy and inspired seekers by singing divine songs which touched the hearts of the most callous listeners. These songs were recorded, and formed the beginnings of the Sikhs' sacred writings, later to become the "Siri Guru Granth Sahib".
Guru Nanak taught his way of life:
Nam Japa - To get up each day before sunrise, to clean the body, meditate on God’s Name and recite the Guru’s hymns to clean the mind. Throughout the day, continuously remember God’s Name with every breath.
Dharam di Kirat Karni - To work and earn by the sweat of the brow, to live a family way of life, and practice truthfulness and honesty in all dealings.
Vand Ke Chakna - To share the fruits of one’s labor with others before considering oneself. Thus, to live as an inspiration and a support to the entire community.
