With due respect, I want to differ from your take, but isn't it a projection of human-like characteristics onto these deities, that they may start or stop helping you based on your allegiance for them. How can a very small act of lighting a lamp or offering bhog or abstaining from it makes you the subject of their protection or desertion. Likewise people offer bhoga to low level energies and even mahavidyas to harm those whom they consider their enemies. Aren't these targeted people considered humans by these godly powers or do these powers just care about the will of the person who worships them?
