When a person is fully conversant with knowledge of the Lord as far as can be known by a perfect living entity in the liberated state, he is allowed to enter into the spiritual sky, where the Vaikuṇṭha planets exist. The Lord was sitting in a lonely place just about to disappear from the vision of the inhabitants of this universe, and Uddhava was fortunate to see Him even at that time and thus receive the Lord’s permission to enter Vaikuṇṭha. The Lord is everywhere at all times, and His appearance and disappearance are merely the experience of the inhabitants of a particular universe. He is just like the sun. The sun does not appear or disappear in the sky; it is only in the experience of men that in the morning the sun rises and in the evening the sun sets. The Lord is simultaneously both in Vaikuṇṭha and everywhere within and without Vaikuṇṭha.
