No amount of planning can completely eliminate the possibility of botching. The idea that 100% of risk can be eliminated with "enough planning" is a pipe dream, a comforting delusion. If one does not care for what one may experience, it's another matter entirely.
One may constant keeps reassuring oneself that "more planning, more certainty"—but this is not how the world works. You can never totally eliminate possible possibilities. Such a level of certainty is nothing but a comfort, fallacious.
But then again, people are more interested in comforting themselves than confronting reality. I maybe can't convince you who reads this, but I think it better for any person to think on this: the truth can't be sedated away, when it comes to it. Better to reflect and admit one's own limits in one's own mind first, before one tries to negotiate with reality, utterly capitulating, and perhaps ending up in more pain than one can imagine.
Unfortunately, suicide is no guarantee. Why should you believe me? The body is incredibly complex, with multifaceted functioning, and can react to opposition in countless ways. The mind is the same, and sensation itself can turn out so many ways.
Distrust those who preach absolute certainty, there is chaos and uncertainty even in death. Whichever way you go, there is no guarantee. The same can be said for life as well. But at least for life, many ends can be sought, whereas total nullification often narrows itself, choking into hard specificity, difficult to manuever, trying to travel into a very tight point. Some people who have hung themselves report an unimaginable sensation of the entire universe downloading into their heads, you push things far beyond what can even suppose to be familiar with. You're telling me that nothing will change much if one's body and mind is pushed into such limits beyond anything experienced? That there is absolute certainty for peace and tranquility, in such an unpredictable maneuver? Death is not a song or harmony but the breaking down of it, of
course the results are unpredictable. For every "peaceful" way to die envisioned, there are many ways unseen where pain, discomfort, in any form they may, may arise unattended, unintended. One cannot have the luxury of total certainty in such an affair.
And surface-level criticisms of "but this way is peaceful and secure" do not address the root nature behind the uncertainty that is inherent to the antiprocess of dying. Ironically, there is anything
but secure… there is a lot to concern about, really, haha. You can't just change reality by indundating it with the same words over and over again. Euphemism cannot rewrite material reality. But words
can grandly change perspective: especially when repeatedly infused, imbibed, injected, inhaled, exhaled, inhaled.
Anyway. Think about the material affects of one's suppositions on one's own mind. Think of
what your methods of thinking affect into, and once this affect is understood (difficult to, results are often a touch uncertain, as manu things), one can begin to make a comparison with what another view of reality may be. Continue to contrast, compare, consider, while noting the curvature of the route one walks along, pondering what wind blows on one along these walkings, consider deeper, continue to ask questions, do not satisfy with absolute certainty, but inquire ever deeper. Inquire ever deeper. This is heart and vein. To inquire ever deeper. One must, one ought to. How else are you to taste a sense of happening of reality without such inquiry? One must be willing to look into the nature of things. And so, in greater sight, comes greater vertigo; in greater clarity, greater gravity of the chaos of all the detail. In all that texture, there is some higher, finer resolution; and when one knows what affects blow upon one's thoughts, inclinations, and knows different perspectives gazing upon what is—one can look deeper, beyond simple suppositions.
So I have no peroration or clarion note on which to close. Beware the irrational, however seductive. Shun the "transcendent" and all who invite you to subordinate or annihilate yourself. Distrust compassion; prefer dignity for yourself and others. Don't be afraid to be thought arrogant or selfish. Picture all experts as if they were mammals. Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence. Suspect your own motives, and all excuses.
