Factually we are related to the Supreme Lord in service. The Supreme Lord is the supreme enjoyer, and we living entities are His servitors. We are created for His enjoyment, and if we participate in that eternal enjoyment with the Supreme Personality of Godhead, we become happy. We cannot become happy otherwise. It is not possible to be happy independently, just as no one part of the body can be happy without cooperating with the stomach. It is not possible for the living entity to be happy without rendering transcendental loving service unto the Supreme Lord.
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.
