Obviously, I don't forget to breathe completely, but I often find myself breathing shallowly, especially at times of stress or impatience.
Breathing consciously is the simplest, most immediate way to change consciousness and feel better.
Now hold it for a few seconds. Now release the breath, and with it, anything else you need to release. One enlightened thought and one is a Buddha, one foolish thought and one is an ordinary person. There is only enlightened activity. If the answer is no, reflect on what in the action, or in your intentions surrounding the action, causes it to be unsupportive of someone, or likely to cause a result that is unhealthy or unloving in some way.
