Changes

The other one, the passive one is simply this: to be concentrated as I have told you, then you open yourself as one opens a door; you see, you have a door here (''gesture at the level of the heart'') and once you are concentrated, you open the door and stay like this (''gesture of immobility''). Or else, you may take another image, as if it were a book, and you open your book very wide with its pages completely blank, that is, quite silent, and you stay like that waiting for what is going to happen. <ref>http://incarnateword.in/cwm/09/7-february-1957#p6,p7,p8 </ref>

''Q. What is the difficulty in keeping … a concentration for all the 24 hours?''

''A.'' The physical being is always fatigued when it is asked to keep a lasting concentration. The concentration can be kept constantly but not by mental decision. It must be a divine decision. <ref>http://incarnateword.in/cwm/16/16-august-1932#p7</ref>

''A.''Perhaps they came and you did not know it! Perhaps it is because you want to concentrate that you become aware that they are there. It may also happen that there is an element of contradiction in the consciousness and that when you want to be silent, something says, "No, I won't be silent!" <ref>http://incarnateword.in/cwm/06/8-september-1954#p30</ref>

This [''stream of thoughts/restless thinking''] is what we call the activity of the mind, which always comes in the way of the concentration and tries to create doubt and dispersion of the energies. It can be got rid of in two ways, by rejecting it and pushing it out, till it remains as an outside force only—by bringing down the higher peace and light into the physical mind. <ref>http://incarnateword.in/cwsa/29/combining-work-meditation-and-bhakti#p36</ref> <ref>http://incarnateword.in/cwsa/31/mental-difficulties-and-the-need-of-quietude#p1 </ref>

It [''the tendency to fall asleep during meditation''] is a common obstacle with all who practise Yoga at the beginning. This sleep disappears gradually in two ways—(1) by the intensifying of the force of concentration—(2) by the sleep itself becoming a kind of swapna samadhi in which one is conscious of inner experiences that are not dreams (i.e. the waking consciousness is lost for the time, but it is replaced not by sleep but by an inward conscious state in which one moves in the supraphysical of the mental or vital being). <ref>http://incarnateword.in/cwsa/29/concentration-and-meditation#p102 </ref>
