There is another phenomenon which is considered spiritual, but which is spiritual only indirectly: it is when you find yourself near someone who has controlled his thought and achieved mental silence. You suddenly feel this silence coming down into yourself and something which was impossible for you half an hour earlier suddenly becomes a reality. This is a rather unusual phenomenon.

== Active Method (Used by Sri Aurobindo) ==
There is an active method by which one looks to see where the thoughts come from and finds they come not from oneself, but from outside the head as it were; if one can detect them coming, then, before they enter, they have to be thrown away altogether. This is perhaps the most difficult way and not all can do it, but if it can be done it is the shortest and most powerful road to silence. <ref>http://incarnateword.in/cwsa/29/concentration-and-meditation#p24</ref>
The principal business of our mind is either a response of acceptance or refusal to these thought-waves (as also vital waves, subtle physical energy waves) or this giving a personal-mental form to thought-stuff (or vital movements) from the environing Nature Force. It was my great debt to Lele that he showed me this. "Sit in meditation," he said, "but do not think, look only at your mind; you will see thoughts coming into it; before they can enter throw them away from you till your mind is capable of entire silence." I had never heard before of thoughts coming visibly into the mind from outside, but I did not think of either questioning the truth or the possibility, I simply sat down and did it. In a moment my mind became silent as a windless air on a high mountain summit and then I saw a thought and then another thought coming in a concrete way from outside; I flung them away before they could enter and take hold of the brain and in three days I was free. From that moment, in principle, the mental being in me became a free Intelligence, a universal Mind, not limited to the narrow circle of personal thought or a labourer in a thought-factory, but a receiver of knowledge from all the hundred realms of being and free too to choose what it willed in this vast sight-empire and thought-empire. <ref>http://incarnateword.in/cwsa/31/thought-and-knowledge#p9</ref>
