Twice.
I've experienced that twice, a real "second coming", a period in which one totally gives up and accepts the Universe as it is.
The first time scared me so badly I sought out an Episcopalian priest, thinking he was Roman Catholic, and then a Catholic priest.
Both times this has happened it has arisen out of the deepest despair I am capable of experiencing. And both times I sold out the experience for ego gratifications, attachments.
They are called "peak experiences" of one wants to research them.
