One's karma

It is impossible to fathom one's karma. Iron, when heated in the flames and pounded, becomes a fine sword. Worthies and sages are tested by abuse. My present exile is not because of any secular crime. It is solely so that I may expiate in this lifetime my past grave offenses and be freed in the next from the three evil paths. 20/3
