If you ctb, I can hardly get the point of being confident your work is done in this life? I guess the reason for ctb would almost always be that you couldn't make it in this life. That you failed at life.
Unless you're very old and have experienced everything.
That is a good point. As with the previous question above, I don't feel confident in asserting any particular rule of thumb because everyone is here with completely unique circumstances.
What I can do is share my own recent experience. My reason for CTB was unbearable physical discomfort (a feeling of having a black hole in my chest) which was caused by chronic emotional pain, in turn caused by failing at life.
However, a few unexpected things happened which have caused me to postpone indefinitely. A lady friend with whom I had shared a passion for Eastern philosophy contacted me out of the blue right when the theme of my life was tying loose ends in terms of unfinished business. On another occasion, I was daydreaming about how I might attempt a recovery if I had a financial windfall, and in that very moment I got a call from my manager giving me the mother of all pay rises. Later, I asked the universe for a sign and my friend contacted me again on the same day. At this point I was sold.
I have turned my attention back to my main guru and can see the errors of my former self; trying to force outcomes that were not meant to be. And buying into the Western notion that success equals being young, attractive, wealthy and popular. The goal of Eastern philosophy is to set ourselves up so that we do not have to go through any rebirths. I am ready to cooperate as needed to make that happen.
