I read that Buddha was able to see all of his past lives, and I realized the only way any of these people could do that is by being outside of time.
We need all three senses of time - a sense of the future, a sense of the present, and a sense of the past - at all times to understand or experience what's happening right now. It's constantly unfolding that way.
Reality includes both the past and the future, but existence includes only the present and is totally dependent on the reality of past and future universes. Without them there is no existence now.
The kinds of mystical experiences that I have had definitely convinced me that I was able to get out of time. I have had experiences, or brief glimpses, of being able to see the future and then come back into time, and then go into extraordinary realms of the past.
