“ I would like to ofer some exercises that can help us use the Five Precepts to cultivate and strengthen mindfulness. It is best to choose one of these exercises and work with it meticulously for a week. Then examine the results and choose another for a subsequent week. These practices can help us understand and find ways to work with each precept. 1. Refrain from killing: reverence for life. Undertake for one week to purposefully bring no harm in thought, word, or deed to any living creature. Particularly, become aware of any living beings in your world (people, animals, even plants) whom you ignore, and cultivate a sense of care and reverence for them too.2. Refraining from stealing: care with material goods. Undertake for one week to act on every single thought of generosity that arises spontaneously in your heart.3. Refraining from sexual misconduct: conscious sexuality. Undertake for one week to observe meticulously how often sexual feelings arise in your consciousness. Each time, note what particular mind states you find associated with them such as love, tension, compulsion, caring, loneliness, desire for communication, greed, pleasure, agression, and so forth.4. Refraining from false speech: speech from the heart. Undertake for one week not to gossip (positively or negatively) or speak about anyone you know who is not present with you (any third party).5. Refraining from intoxicants to the point of heedlessness. Undertake for one week or one month to refrain from all intoxicants and addictive substances (such as wine, marijuana, even cigarettes and/or caffeine if you wish). Observe the impulses to use these, and become aware of what is going on in the heart and mind at the time of those impulses (88-89). ”
