The scientist Freeman Dyson shared his mystical experience of "cosmic unity" he had as a teenager.
Many people want to know the ultimate nature of the universe, the ultimate reality. Many seek it through science. But mysticism and contemplation may offer the Way that actually realizes that One, which is Love.
As science seeks a unified theory of everything, of reality as a whole, we may need to focus more on contemplating the nature of consciousness and our own self to find the answer.
Where does spacetime come from? Might our mind generate it as a kind of illusion in consciousness? How might we transcend this illusion in contemplation?
We tend to think of objects as self-contained things that move through something else we call spacetime, but this distinction may not be fundamental. We may actually be seeing something fundamentally changeless in excited states.
Some think we have to qualify for God's Love, that it is something God only gives through religious obedience. Mysticism says not quite.
A quote often attributed to St. Francis doesn't seem to have a credible source, but it's still a good saying, and others appear to have said similarly.
What is there to do if we are already inseparable from the One? If we are already That, what could we do?
Paul talks about "Christ" as the One, and persons as the parts that make up that One.
