They (small Buddhist sects) sit down for a few hours in the day and even at night and quiet their mind. This is for them the key to all realisation—a quiet mind that knows how to keep quiet for hours together without roving. You must not believe however that it is a very easy thing to do, but they have no other object. They do not concentrate upon any thought, they do not try to understand better, to know more, nothing of the kind; for them the only way is to have a quiet mind and sometimes they pass through years and years of effort before they arrive at this result—to silence the mind, to keep it absolutely silent and still; for, as it is said here in the Dhammapada, if the mind is unbalanced, then this constant movement of ideas following one another, sometimes without any order, ideas contradicting and opposing each other, ideas that speculate on things, all that jostles about in the head, makes holes in the roof, as it were. So through these holes all undesirable movements enter into the consciousness, as water enters into a house with a leaky roof. <ref>http://incarnateword.in/cwm/03/conjugate-verses#p87</ref>
=== Concentrating Upwards in Aspiration ===
It is quite certain that to create absolute silence is of all things the most difficult, for many things of which one was not aware, become enormous! There were all kinds of suggestion, movements, thoughts, formations which went on as though automatically in the outer consciousness, almost outside the consciousness, on the frontiers of consciousness; and as soon as one wants to be absolutely silent, one becomes aware of all these things which go on moving, moving, moving and make a lot of noise and prevent you from being silent. That is why it is better to remain very quiet, very calm and at the same time very attentive to something which is above you and to which you aspire, and if there is this kind of noise passing like that around you (Mother moves her hands around her head), not to pay attention, not to look, not to heed it. If there are thoughts which go round and round and round like this (gestures), which come and go, do not look, do not pay attention, but concentrate upwards in a great aspiration which one may even formulate—because often it helps the concentration—towards the light, the peace, the quietude, towards a kind of inner impassiveness, so that the concentration may be strong enough for you not to attend to all that continues to whirl about all around. But if suddenly you say, "Ah, there's some noise! Oh, here is a thought!", then it is finished. You will never succeed in being quiet. Have you never seen those people who try to stop a quarrel by shouting still louder than the ones who are quarrelling? Well, it is something like that. (''Mother laughs'') <ref>http://incarnateword.in/cwm/06/8-september-1954#p32</ref>
Above all words, above all thoughts in the luminous silence of an aspiring faith give yourself totally, unreservedly, absolutely to the Supreme Lord of all existences and He will do of you what He wants you to be. <ref>http://incarnateword.in/cwm/14/self-giving#p39</ref>
