When you sit down to meditate, it sometimes happens that your mind still has some unfinished business. It is best to finish up all mental preoccupations prior to entering meditation or, if you still have such thoughts lingering as you begin meditation, put them to rest as quickly as possible and gently bring your attention to your body and see how it feels. This determination and gentle attitude allows us to avoid the habit of rushing through things just to get them over and done with. In meditation, quality is more important than speed. This key point should never be forgotten. When the mind is present with the body, you feel differently from the way you normally feel seated at work or when eating and so forth. You become more relaxed, there is a feeling of rest, and a sense of blessing can appear to your awareness. When you experience relaxation and a vast sense of openness, this indicates that your mind and body are together, unified, and in harmony.
