Repentance should ideally be practiced at the end of each day. We should sit down and meditate as we try to recall the best we can, any misgivings we have done in the day. For repentance to be more effective, misdeeds should be recalled as specifically as possible, instead of vaguely generalizing. Doing this practice daily reduces our repetitive mistakes as it increases our mindfulness the next day. Repentance should also be practiced immediately in the moment, without procrastination, when we realize we have just made a mistake. If one's pride is too strong, one should still make a point to repent later, as soon as possible.
The stronger our sincerity is, the more powerful our repentance becomes. It is important to understand that repentance does not erases our negative karma, but it can dissolve its future effects, much like the addition of abundant pure water onto salt, which dissolves the otherwise unbearable saltiness we have to taste.
