It is essential to maintain the continuity of meditation day after day, because in this way your practice gradually gains substance and stability. It is like the way a small trickle of water little by little turns into a stream and then a river. The traditional texts state that it is better to meditate regularly and repeatedly for short periods of time than to do long sessions every now and then. For example, you could devote 20 minutes a day to meditating formally and also take advantage of short breaks in your daily activities to recall the experience you had during your formal sessions, even if only for a few moments.
