Do you think synchronicity is meaningful?
I've never experienced any such coincidences.
If you said yes:
Synchronicity is a sign of Divine Providence, or some other manifestation of God's Will.
Synchronicity is a sign of an underlying order in the Universe, such as fate, but not necessarily a sign of a deity at work.
Synchronicity is manifested by the will/brainwaves/something of humans.
Synchronicity is proof of the human ability to recognize patterns in the random.
Synchronicity can best be described by something I will type in a comment.
