In the Vedic literature the definition of God is also there, who is God. Now everyone is claiming, "I am God," but they do not know what is God. They are falsely claiming. But if you find out Parasara-sūtra, there is definition of God. What is that? Aiśvaryasya samagrasya (Viṣṇu Purāṇa 6.5.47). God is the owner of all wealth; vīryasya, all strength; yaśasaḥ, all fame; all intelligence; all beauty and all renunciation. These six items in full strength, cent per cent possession, that makes the God. So our position is always subordinate according to Vedic literature or any literature. If you reject God, then you will have to select somebody else you will have to worship as God.
Take for example Lord Buddha. Lord Buddha's philosophy that there is no question of God, but we are suffering due to this material encagement and combination of matter. This body is combination of matter, and when the matter is dismantled, which is called nirvāṇa, then there is no question of feeling pains and pleasure. That is Buddha philosophy.
But there is no question of God there. But fortunately or unfortunately, they are worshiping Lord Buddha. Try to understand that personality cannot be imagined at any circumstance. Somebody has to be found out. So the Vedas gives us the information that you accept the leadership of the Supreme Personality of Godhead. Then everything, all questions, all problems will be solved.
