Jesus also said "Seek ye the Kingdom of Heaven which is within." This is the same thing which is said in pretty much of all the Eastern and other esoteric traditions, and it refers basically to a state of consciousness, not a place or an outer phenomenon. I think that fundamentalists are mistaken in assuming it to be an outward event when it is in fact an inner change in consciousness that is being referred to.

The esoteric traditions (in a great many religions) also refer to God as being within each person, and God-consciousness as something every person can therefore attain to. God-consciousnes would be a state where one completely lets go of fear and completely embraces love (every form of love). If a person did that, they would be in a heavenly state of consciousness and would, in effect, be experiencing the Kingdom of Heaven.

Imagine what it would be like to have no fear and to feel absolute love. Imagine the energy it would give a person and how much creativity it would bring forth. To me, that would be Heaven.
