These teachings are like a raft, to be abandoned once you have crossed the flood. Since you should abandon even good states of mind generated by these teachings, How much more so should you abandon bad states of mind!
Gautama BuddhaWhatever an enemy might do to an enemy, or a foe to a foe, the ill-directed mind can do to you even worse.
Gautama BuddhaFor, owners of their deeds (karma) are the beings, heirs of their deeds; their deeds are the womb from which they sprang; with their deeds they are bound up; their deeds are their refuge. Whatever deeds they do-good or evil-of such they will be the heirs. And wherever the beings spring into existence, there their deeds will ripen; and wherever their deeds ripen, there they will earn the fruits of those deeds, be it in this life, or be it in the next life, or be it in any other future life.
Gautama Buddha
