Ajuni
He is Without Birth or Beginning
God has no birthday. He was never born. That which is born must one day die. God is beyond birth and death. So is the Aatmaa. What is born is the body, not the Aatmaa and what dies is also the body, not the Aatmaa.
Not recognizing our true nature, we identify with the perishing and ever-changing body-mind-intellect complex and consider ourselves to be the limited entity called jeeva. This deluded jeeva or 'ego' asserts to itself the sense of doer-ship and enjoyer-ship, and according to its desires and actions or vassanas and karmas, is forced to take up various bodies or junees to enjoy or suffer the result of its actions. Thus it remains entangled in the cycle of birth and death called sansaara.
Ishwara or the Lord has no ignorance or ego, therefore no vaasanas or karmas. So He does not have to take up any form and undergo the experiences of life forms such as plants, animal or human. That is why He is also called Ajuni.
However, out of love and compassion for His devotees, and with full knowledge of His own nature, He manifest Himself by His own maya. Such a manifestation of the Lord is called an avtaara. He who in devotion surrenders to the Lord and realizes His own true nature as the Aatmaa, which is ajuni, 'unborn', is freed from the cycle of birth and death.
Go is the one changeless cause of the universe. Still, someone may ask, "If God created the entire universe, who created God?" Children very often ask that question, don't they? Shri Guru Nanakji says, "He is Saibangh."
