Tamāla Kṛṣṇa: "Their pleasures and displeasures are dependent on the performance of yajñas by human beings. Some of the yajñas are meant for satisfying the particular demigods, but even in so doing Lord Viṣṇu is worshiped in all yajñas as the chief."
Prabhupāda: Just like if you obey the department, say, the police department. You are obeying the police department means you are obeying the government. Nobody can manufacture a police department and force you to obey. Because it is one of the important department of government, therefore as soon as there is police handcuff you have to stop. You may be very rich man, millionaire, but you have to obey the orders of the police, otherwise you will be prosecuted. And wherefrom. That man is an ordinary man; simply he stops you. Why do you stop? Because you obey the government.
Similarly, all obeisances offered to the demigods, they are meant for giving obeisances to the Supreme Lord. That is the beginning. Go on.
