In this material world there are only two representatives of the Supreme Personality of Godhead; the transcendental sound vibration of the Holy Name and his eternally transcendental deity incarnation.
You want to see God through your material eyes, so God manifests through matter in the form of a deity.
By taking darshana of the archavigraha, the deities, our attachment to our body fades away.
One who does not accept the transcendental form of the Lord is certainly an agnostic. Such a person should be neither seen nor touched. Indeed, he is subject to be punished by Yamaraja [the lord of death].
