There are different kinds of bad deeds but, no matter what kind of bad deed you have committed, after each one you should feel repentant and try to erase the effects of your bad deed by doing a good deed. p. 239
The fact is that every bad deed you commit can pollute your soul. Cleanse it then by your tears, or by some other kind of penitent behaviour. You must never fail to purify your mind and your heart when you find that they have been polluted by bad actions. p. 239
Doing good deeds after bad deeds, is a method of reconditioning one’s mind. This practice is not exactly easy. But it is an important psychological process. By engaging in it, one reprocesses one’s thinking. In physical terms, what would be a process of washing out is, in psychological terms, a correction of one’s way of thinking. p. 239

This process has a very important positive effect. It helps in the development of one’s mind. Thus your mistake can be turned into an act of intellectual development. Any mistake that leads to intellectual development can form the basis of a good and healthy practice. p. 239
If your mistake gives you a positive lesson, then it is an experience rather than a mistake. If your bad deed motivates you to do a good deed, then in terms of its result, it is a good rather than a bad occurrence. p. 239
Such a practice keeps your mind alive, in that it activates your thinking capacity. This practice awakens your mental faculties, making you like a traveler who has had some advantageous break in his journey, before finally reaching his destination. p. 239
If you commit an evil deed, do not fall into despair, but re-plan your life along better lines and surely you will be a success. p. 240
