During the Second World War, a man in Calcutta worshiped Hitler because thanks to that war he had amassed a large amount of wealth by dealing in the black market. Similarly, those in the modes of passion and ignorance generally select a powerful man to be God. They think that anyone can be worshipped as God and that the same results will be obtained.
Now, it is clearly described here that those who are in the mode of passion worship and create such gods, and those who are in the mode of ignorance, in darkness, worship dead spirits. Sometimes people worship at the tomb of some dead man. Sexual service is also considered to be in the mode of darkness. Similarly, in remote villages in India there are worshipers of ghosts. We have seen that in India the lower class people sometimes go to the forest, and if they have knowledge that a ghost lives in a tree, they worship that tree and offer sacrifices. These different kinds of worship are not actually God worship. God worship is for persons who are transcendentally situated in pure goodness. In the Śrīmad-Bhāgavatam it is said, sattvaṁ viśuddham vāsudeva-śabditam. “When a man is situated in pure goodness, he worships Vāsudeva.” The purport is that those who are completely purified of the material modes of nature and who are transcendentally situated can worship the Supreme Personality of Godhead.
