You will have many ways to realize the conditions coming may be quite hellish and tough. Always always be kind to yourself unless you feel hatred against others. If you feel hatred against others, repent, right away. Beg God for mercy of the enlightnment kind and ask Buddha or Jesus to accompany you forever especially until you die so you can learn and gain merit just the right way with what is your kamma left.

In hell, exaltation is possible and without drugs whatsoever. Stavation is a prayer and a skill of meditating. Read Milarepa songs when you are hungry. And make tea with lemon or green leaves if you can. Milarepa went stark raving mad and starved almost to death. Yet he is a much  very beloved saint of Tibet. Perfect for identification with what is to come and to call on as a Friend. He has seen starvation the best.

He was called upon when I was starving in autumn 2005. He appeared as a friend and an impression of his wisdom touched my soul. I had no real vision but my mind was wild at the time. So he simply kept me company with his divine wild mind. i was a meeting of energy. That felt like a meetingof his mind. Wonderful impression and very very satisfying to recall him in our minds when hungry. he knows it very very well. drink tea- hot water with lemon is best. Buy yourselves big containers of lemon juice if you plan on going on a forced fast. please dont buy more than 5 bottles in two weeks. Otherwise, it will be wasted and no one else will get any.
