The most important thing is self-remembering. You must try to remember yourselves at least once a day, and you must do it willingly, from yourselves. All other work on oneself ultimately depends on self- remembering. Only half a minute is necessary, and even if it consists in nothing else than stopping your thoughts and trying to relax everything, it is better than nothing. Don't think about self-remembering, but do it.

At first it is best to do it at some definite time that you decide upon. The first sign that you are doing it rightly is that you have a distinct feeling of force entering you, as if something had opened in you. Immediately you feel this, stop. You must stop instantly, and forget about the whole thing.
