Changes

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>

This work of mental purification should be done very regularly in order to secure a complete control over one’s actions. For this purpose, it is good to set apart some time every day when one can quietly go over one's thoughts and put one's synthesis in order. Once the habit is acquired, you can maintain control over your thoughts even during work and action, allowing only those which are useful for what you are doing to come to the surface. Particularly, if you have continued to cultivate the power of concentration and attention, only the thoughts that are needed will be allowed to enter the active external consciousness and they then become all the more dynamic and effective. And if, in the intensity of concentration, it becomes necessary not to think at all, all mental vibration can be stilled and an almost total silence secured. In this silence one can gradually open to the higher regions of the mind and learn to record the inspirations that come from there. <ref>http://incarnateword.in/cwm/12/mental-education#p19</ref>
