Indirect worship of God Vs direct worship of contemporary human incarnation

In the indirect worship, the worship is not aimed at the model but it is aimed at the God only. God is pleased to some extent in such worship also because the aim is God only. Of course, in the direct worship God is extremely pleased because God, who always exists in the human form only and receives your service directly. God does not exist in the inert objects (Natasya pratima asti… Veda) but still He is pleased in such worship also because the aim is God only. People worship salagrama (a piece of stone) as a representative model of Vishnu (God). Here, the worship is aimed at Vishnu and not aimed at the stone.

Sumati worshipped her husband Kaushika as God. Kaushika is the greatest sinner and was ready to go to hell. But from such worship of Kaushika, Sumati derived super power to stop the sunrise! Only God controls the sun (Bishodeti suryah … Veda). The wretched Kaushika cannot give such power to Sumati. This power is derived from God only because when Sumati worshipped her husband as God, the worship was aimed at God and not aimed at Kaushika. Kaushika was a representative model of God for Sumati like the petty stone (salagrama) representing the all-pervading Lord Vishnu. If that is the power of Sumati obtained from indirect worship of God, what shall be power of a devotee who worships God directly through the service to the contemporary human incarnation? Hanuman worshipped Rama who was His contemporary human incarnation and became God and controlled the sun forever. Veda says that the sun moves constantly due to the fear to God. Even in His childhood He was meditating upon Rama introduced by His mother and the result of that was the power to swallow the sun like a fruit!
