Dear As per vedas there is only one God who nurses destroys and creates.Vedas talk of only one almighty form less God interestingly Brahma, Vishnu, Shiva by these sanskrit names one god is referred to in Vedas.Our ancestors used to keep the name their progenies from these vedas. They all were philosher of vedas and yoga, they were consulted by even Kings for guidance and conduct.There used to be shstrath among them to come to a conclusion note not imposition of thoughts.However LOrd Rama, Hanuman and Loed Krishna were highly advanced souls who have studied this knowledge from respective Gurus. I hope You all know.Vedas do not talk of idol worship.
