In the Vedas it is said that persons who are attached to demigods to the exclusion of the Supreme Personality of Godhead are like the animals who follow the herdsman even though they are taken to the slaughterhouse. The materialists, like animals, also do not know how they are being misdirected by neglecting the transcendental thought of the Supreme person. No one can remain vacant of thought. It is said that an idle brain is a devil's workshop because a person who cannot think in the right way must think of something which may bring about disaster. The materialists are always worshiping some minor demigods, although this is condemned in the Bhagavad-gita (7.20). As long as a person is illusioned by material gains, he petitions the respective demigods to draw some particular benefit which is, after all, illusory and nonpermanent. The enlightened transcendentalist is not captivated by such illusory things; therefore he is always absorbed in the transcendental thought of the Supreme in different stages of realization, namely Brahman, Paramatma and Bhagavan. In the previous verse it is suggested that one should think of the Supersoul, which is one step higher than the impersonal thought of Brahman, as it was suggested in the case of contemplating the virat-rupa of the Personality of Godhead.
