In the Bhagavad-gītā, worship of different demigods or rendering service to them is not approved. It is stated in the Seventh Chapter, twentieth verse:
- kāmais tais tair hṛta-jñānāḥ
- prapadyante 'nya-devatāḥ
- taṁ taṁ niyamam āsthāya
- prakṛtyā niyatāḥ svayā
"Those whose intelligence has been stolen by material desires surrender unto demigods and follow the particular rules and regulations of worship according to their own natures." Here it is plainly said that those who are directed by lust worship the demigods and not the Supreme Lord Kṛṣṇa. When we mention the name Kṛṣṇa, we do not refer to any sectarian name. Kṛṣṇa means the highest pleasure, and it is confirmed that the Supreme Lord is the reservoir or storehouse of all pleasure. We are all hankering after pleasure. Ānanda-mayo 'bhyāsāt (Vedānta-sūtra 1.1.12). The living entities, like the Lord, are full of consciousness, and they are after happiness. The Lord is perpetually happy, and if the living entities associate with the Lord, cooperate with Him and take part in His association, then they also become happy.
The Lord descends to this mortal world to show His pastimes in Vṛndāvana, which are full of happiness. When Lord Śrī Kṛṣṇa was in Vṛndāvana, His activities with His cowherd boyfriends, with His damsel friends, with the other inhabitants of Vṛndāvana and with the cows were all full of happiness. The total population of Vṛndāvana knew nothing but Kṛṣṇa. But Lord Kṛṣṇa even discouraged His father Nanda Mahārāja from worshiping the demigod Indra, because He wanted to establish the fact that people need not worship any demigod. They need only worship the Supreme Lord, because their ultimate goal is to return to His abode.
