The Lord is manifested in different expansions. He is the root of the complete tree. He is the stomach of the complete body. As such, pouring water on the root is the right process to water the tree, as much as feeding the stomach supplies energy to all the parts of the body. Srila Vyasadeva should not have compiled any Puranas other than the Bhagavata Purana because a slight deviation from that may create havoc for self-realization.
If a slight deviation can create such havoc, then what to speak of deliberate expansion of the separatist idea from the Absolute Truth Personality of Godhead. The most defective part of worshiping demigods is that it creates a definite conception of pantheism, ending disastrously in many religious sects detrimental to the progress of the principles of the Bhagavatam, which alone can give the accurate direction for self-realization in eternal relation with the Personality of Godhead by devotional service in transcendental love.
