The faculty of concentrated attention can be developed scientifically by a methodical training the same way as an athlete develops methodically his muscles. The power of concentration can be developed in such a way that concentration is obtained at will and on whatever subject or activity is chosen. <ref>http://incarnateword.in/cwm/12/concentration-and-dispersion#p5 </ref>
Concentration consists precisely in removing the cloud.
You gather together all the elements of your intelligence and fix them on one point, and then you do not even try actively to find the thing. All that you do is to concentrate in such a way as to see only the problem—but seeing not only its surface, seeing it in its depth, what it conceals. If you are able to gather together all your mental energies, bringing them to a point which is fixed on the enunciation of the problem, and you stay there, fixed, as though you were about to drill a hole in the wall, all of a sudden it will come. And this is the only way. <ref>http://incarnateword.in/cwm/05/24-june-1953#p51 </ref>
The method is always the same. Gather together the energies in you that are usually dispersed outside; concentrate your consciousness within, beneath the surface agitation, and establish, as far as possible, a perfect quietness in your heart and head; then formulate your aspiration, if you have one, and open yourself to receive the divine force from above. <ref>http://incarnateword.in/cwm/ 17/ 1- july- 1960# p6</ref>
While engaging in work, you must become what you are doing and not remain a small person looking at himself doing it; for if one looks at oneself acting, one is still in complicity with the ego. It is through concentrated attention that one can do things quickly and one does them much better. <ref>http://incarnateword.in/cwm/04/26-april-1951#p33 </ref> When you want to realise something, you make quite spontaneously the necessary effort; this concentrates your energies on the thing to be realised and that gives a meaning to your life. This compels you to a sort of organisation of yourself, a sort of concentration of your energies because it is this that you wish to do and not fifty other things which contradict it. And it is in this concentration, this intensity of the will, that lies the origin of joy. This gives you the power to receive energies in exchange for those you spend. <ref>http://incarnateword.in/cwm/04/13-january-1951#p15</ref>
