Thou art That
A spontaneous event is a completely mysterious one.
That depends. If one is attached to a rational mode of thought, the spontaneous appears as being paradoxical. IOW, the rational mind is the kind of mind that is always seeking a way to 'figure things out', and which holds preconceived notions about what comes next, but because the nature of the spontaneous is non-rational, there is paradox.
OTOH, if the mind is held 'slightly ajar; the spontaneous event can be a truly enlightening one, as the famous Japanese Haiku poem signifies:
Furu ike ya
kawazu tobikomu
mizu no oto
old still pond,
frog,
leapsplash
Zen calls this unexpected aural event 'a letter from home', which is the awakening of Original Mind.
