It is always better to try to concentrate in a centre, the centre of aspiration, one might say, the place where the flame of aspiration burns, to gather in all the energies there, at the solar plexus centre and, if possible, to obtain an attentive silence as though one wanted to listen to something extremely subtle, something that demands a complete attention, a complete concentration and total silence. And then not to move at all. Not to think, not to stir, and make that movement of opening so as to receive all that can be received, but taking good care not to try to know what is happening while it is happening, for if one wants to understand or even to observe actively, it keeps up a sort of cerebral activity which is unfavourable to the fullness of the receptivity -to be silent, as totally silent as possible, in an attentive concentration, and then be still.
If one succeeds in this, then, when everything is over, when one comes out of meditation, some time later -usually not immediately -from within the being something new emerges in the consciousness: a new understanding, a new appreciation of things, a new attitude in life- in short, a new way of being.
