What is the destination (rebirth) of a person with Vibhava Tanha?
Is Vibhava Tanha some kind of partial Nibbana?
There are three kinds of Tanha. (Kama, Bhava, Vibhava) some description of Vibhava Tanha:
“And how do some slip right past? Some, feeling horrified, humiliated, & disgusted with that very becoming, relish non-becoming: ‘When this self, at the break-up of the body, after death, perishes & is destroyed, and does not exist after death, that is peaceful, that is exquisite, that is sufficiency!’ This is how some slip right past.
