What is the point of Buddhist worship when there is no god?
Buddhism is a philosophy, not a religion. It does not involve worship at all.
Buddhist people do not worship because neither they believe in God nor consider Buddha himself is God who can fulfill their wishes. However Buddhist people go to Buddha Vihara or Pagoda to pay respect to their great teacher i.e Buddha who has shown them a path to overcome sufferings. In the Buddha Vihara Buddhist people pray and meditate for the purification of mind.
Buddhists do not worship, in the sense of Christian worship of God. We worship no god or persons. Our prayers serve a different purpose also. The purpose of Buddhist prayer is to awaken our inherent inner capacities of strength, compassion and wisdom rather than to petition external forces for guidance or deliverance. Buddhist do show reverence to The Buddha and his teachings at alters in temples and in our homes.
Buddhist do not have a supreme being as a supreme being is not really part of a Buddhist philosophy. Some Buddhist believe in god, some believe in many gods, many however are atheist or agnostic. So the Buddhist religion really does not worship or identify a supreme being, I guess that is up to the individual Buddhist.
