"(religion) any doctrine of religious philosophy and mysticism claiming that knowledge of God can be attained through mystical insight and spiritual ecstasy, and that direct communication with the transcendent world is possible"

Concerning religion, Does Buddism, Taoism, Confucious, any European religion beside Christian accept there is but one God, Some of the religions claim there's more than just one? Have I misunderstood the definition of theosophy? Each religion has it's own history and understanding by it's believers.Paul
