"Satori", now an English word, thanks to its introduction by D.T. Suzuki, has come to imply omniscient wisdom.
I much prefer the term KENSHO, which holds the more modest meaning of "seeing into (essential) nature."
"Shunyata", the void, expresses deepest experience ---
but I find that all too readily it becomes something abstract called "nothing."
