In order to carry out a practice — such as constantly watching the mind — you should form a determination, make a pledge, right when you wake up: “Now, for the rest of this day, I will put into practice what I believe just as much as I can.” It is very important that, at the start of the day, we should set out to shape what will happen later. Then, at the end of every day, check what happened. Review the day. And if you carried through for that whole day your morning’s determination, then rejoice. Reinforce further your motivation to continue in the same line. However, when you do your reviewing, you may discover that you did things during the day that are contrary to your religious values and beliefs. You should then acknowledge this and cultivate a deep sense of remorse. Strengthen your resolve not to indulge in these actions in the future.
