Kaisipang Hudyo sa Mga Kawikaan 9:12: Duties

If you conduct yourself in this kind of zeal and effort for the rectification of your body, in spite of its lowliness and baseness, and despite your weak capacity to save it from damage or to benefit it, how much more is it your duty to conduct yourself with this zeal and effort for the rectification of your soul, which is so important and which you will be left with (forever), and which you were commanded to guide its matter, and to look into things which will rectify it in acquiring wisdom and understanding, as written: "Buy the truth, and sell it not" (Mishlei 23:23), and "Get wisdom, get understanding" (Mishlei 4:5), and "How much better is it to get wisdom than gold! and to choose understanding rather than silver!" (Mishlei 16:16), and "So shall the knowledge of wisdom be unto your soul" (Mishlei 24:14), and "If you are wise, you shall be wise for yourself" (Mishlei 9:12), which means that the spiritual acquisitions are yours. No one can ever steal them from you, unlike what occurs by physical acquisitions.

All this is possible for a man during his lifetime, if he lives long enough, and only if his intent is to repent and cleanse his soul of its sin before his Creator. Concerning such a penitent, the wise man said: "If you are wise, you are wise for yourself, And if you scoff, you alone will bear it" (Mishlei 9:12).
