Does any property owner never visits his properties?
Does any King never visits his kingdom?
Does any President/Prime Minister of a country, never visits places in his country?
Does any father/mother never visits his/her children?
In a similar way, the Supreme property owner, the Supreme King, the Supreme President, the Supreme Father, does visit His creations. There is only one religion where God is known to have appeared and performed His miraculous pastimes. Not just once, but millions of times. This religion is Sanatan-Dharma, the Eternal Religion. All other religions are not Sanatan (eternal) and they have absolutely no idea on His appearances and His description.
“Although I am unborn and My transcendental body never deteriorates, and although I am the Lord of all living entities, I still appear in every millennium in My original transcendental form.” (Lord Krishna, Bhagavad-Gita 4.6)
In this verse the word ‘millennium’ means one daytime of Brahma. There is no word in the English dictionary to describe such a period of time and thus the word ‘millennium’ is used as best fit. Lord Krishna appears in His original Krishna form, once in every daytime of Brahma. One day (24 hours) of Brahma is 8.64 billion years. Thus Lord Krishna appears once in every 8.64 billion years.
The appearance of Lord Krishna in His original form is also confirmed in the Caitanya-caritamrta.
“Once in a day of Brahma, he descends to this world to manifest his transcendental pastimes.” (Caitanya-caritamrta Adi-Lila 3.6)
God is Unborn?
God is not born like us through the womb of a mother. We come out from the womb of a mother and we are naked. When Lord Krishna appeared 5000 years ago. He just appeared next to a women and He was fully clothed. This is one of the differences between us and God. We come out from the womb of a mother and are naked, but He just appears and is fully clothed. Also He does not go through old age, disease, and misery like us. In this sense, God is unborn.
