How the best philosophers understand demigod worship

Uttamas tu harim prahus taratamyena tesu ca: such philosophers are the best because they know that the Supreme Personality of Godhead reveals Himself differently to worshipers in various modes of material nature. They know that there are thirty-three million demigods just to convince the conditioned soul that there is a supreme power and to induce him to agree to worship one of these demigods so that by the association of devotees he may be able to understand that Krsna is the Supreme personality of Godhead.
