Guru Nanak Dev Ji (Punjabi: ਗੁਰੂ ਨਾਨਕ; Hindi: गुरु नानक, Urdu: گرونانک [ˈɡʊɾu ˈnɑnək] Gurū Nānak) (15 April 1469 – 22 September 1539) was the founder of the religion of Sikhism.
"Nanak, the founding Master of the Sikh religion in the sacred land of the Vedas, taught the path of the heart. Nanak taught fraternity among all religions, schools, sects, etc. When we attack all religions or any religion in particular, we commit the crime of violating the law of the heart. In the heart temple, there is a place for all religions, sects, orders, etc. All religions are precious pearls strung on the golden thread of the divinity. Our Gnostic Movement is made up by people of all religions, schools, sects, spiritual societies, etc. In the heart temple there is place for all religions, for all forms of worship. Jesus said, "In loving one another thou shalt prove that thou art my disciples." The Sikh scriptures, like those of every religion, are truly ineffable." - Samael Aun Weor
"When we are in the physical world, we must learn to be awake from moment to moment. We then live awakened and self-conscious from moment to moment in the internal worlds, both during the hours of the sleep of the physical body and also after death."
