Meditation Retreats

Ever come across Meditation Retreat that requires you to observe 5 or 8 precepts? Do you know them? I listed them down briefly so that you can remember well, they are :

1. Avoid Killing;
2. Avoid Stealing;
3. Avoid engaging in activities that focus on sensual experience;
4. Avoid speaking;
5. Avoid intoxicants
6. Avoid overeating;
7. Avoid activities that arouse the emotions and scatter the mind;
8. Avoid slackening our resolve.

These eight precepts support the arising of the wholesome mental states that lead to concentration and wisdom. I sometimes find difficulties to observe all the eight precepts, especially the overeating part. But I guess these are precepts that we have to follow if we were to go for Meditation Retreat
