Prayopavesa is the best method. It takes a month to several years to complete. In the end, you literally die from LDAR. During the process, you have time empty your mind of all desires, hope, and will to live. The euphoria caused by the fasting makes it feel like a suicide dream. There is no emotion, just the conscience decision that "I'm done"... Nothing matters, nothing has meaning, everything is the result of chaos, your life is insignificant and filled with suffering caused by factors totally out of your control, there is no logical reason to continue living. To wither away, longing for emptiness rather than defined, physical suffering witnessed constantly by the senses... is to chose wisdom and mercy for yourself rather than struggling in life as an inferior specimen, competing for prizes that are worthless, and dying in shame and desperation like beasts bound by their instincts and mortality.
