Ultimate serenity is the coming to rest of all ways of taking things, the repose of named things; no truth has been taught by a Buddha for anyone, anywhere.
Something might be true while being harmful and dangerous in the highest degree. Indeed, it might be a basic characteristic of existence that those who know it completely would perish, in which case the strength of a spirit should be measured according to how much of the 'truth' one could still barely endure- or to put it more clearly, to what degree one would require it to be thinned down, shrouded, sweetened, blunted, falsified.
...And these vicissitudes come best in youth;
For when they happen at a riper age,
People are apt to blame the Fates, forsooth,
And wonder Providence is not more sage.
Adversity is the first path to truth:
He who hath proved war, storm, or woman's rage,
Whether his winters be eighteen or eighty,
Has won experience which is deem'd so weighty.
Since an intelligence common to us all makes things known to us and formulates them in our minds, honorable actions are ascribed by us to virtue, and dishonorable actions to vice; and only a madman would conclude that these judgments are matters of opinion, and not fixed by nature.
