Bhagavad-gītā (7.20) says, kāmais tais tair hṛta jñānāḥ prapadyante ’nya-devatāḥ: “Those whose minds are distorted by material desires surrender unto the demigods.” Similarly, this verse condemns worship of the demigods. We may show our respect to the demigods, but the demigods are not worshipable. The intelligence of those who worship the demigods is lost ( hṛta jñānāḥ ) because these worshipers do not know that when the entire material cosmic manifestation is annihilated, the demigods, who are the departmental heads of that manifestation, will be vanquished. When the demigods are vanquished, the benedictions given by the demigods to unintelligent men will also be vanquished. Therefore a devotee should not hanker to obtain material opulence by worshiping the demigods, but should engage in the service of the Lord, who will satisfy all his desires.

“Whether full of all material desires, free from material desires or desiring liberation, a person who has broader intelligence must by all means worship the supreme whole, the Personality of Godhead.” ( Bhāg. 2.3.10 ) This is the duty of a perfect human being. One who has the shape of a human being but whose actions are nothing but those of an animal is called nara-paśu or dvipada-paśu, a two-legged animal. A human being who is not interested in Kṛṣṇa consciousness is condemned herewith as a nara-paśu.
