No people can worship however, whatever and whomever they please. Brahman is happy either way. S/He is not so filled with petty jealousy or hubris to care.I endorse friend @SomeRandom that not only metaphors but all poetic tools might have been used in Veda.
But I don't endorse him on that idols or statues are metaphors and supported by the Veda scripture and are needed in the worship houses, these are nothing but distractions from Brahman. Brahman does not need them. Right? Please
