For all this movement of knowledge which we are describing is a method of purification and liberation whereby entire and final self-knowledge becomes possible, a progressive self-knowledge being itself the instrument of the purification and liberation. <ref>http://incarnateword.in/cwsa/23/the-release-from-the-heart-and-the-mind#p9</ref>
== Key to Purification ==
=== Love ===
In this way it is not necessary to introduce the principle of love into the explanation. But if you want to know or understand the nature of the Force or the Power that enables or brings about this transformation—particularly where evil is concerned, but also with ugliness to a certain extent—you see that love is obviously the most potent and integral of all powers—integral in the sense that it applies in all cases. It is even more powerful than the power of purification which dissolves all bad will and which is, as it were, the master of the adverse forces, but which has not the direct power of transformation. The power of purification first dissolves in order to allow the transformation afterwards. It destroys one form in order to be able to create a better one, whereas love need not dissolve in order to transform; it possesses the direct power of transformation. Love is like a flame that changes what is hard into something malleable and even sublimates this malleable thing into a kind of purified vapour—it does not destroy, it transforms. <ref> http://incarnateword.in/cwm/10/aphorism-49#p12 </ref>
The love that one contains in silence acts within oneself for purification and transformation. The love that one turns outwards—if one does it in a pure and disinterested way—may occasionally help others. But most often they receive it wrongly... So you must do as your instinct guides you. <ref>http://incarnateword.in/cwm/17/24-july-1934#p3</ref>
=== Surrender ===
There are two possibilities, one of purification by personal effort, which takes a long time, another by a direct intervention of the Divine Grace which is usually rapid in its action. For the latter there must be a complete surrender and self-giving and for that again usually it is necessary to have a mind that can remain quite quiet and allow the Divine Force to act supporting it with its complete adhesion at every step, but otherwise remaining still and quiet. This last condition which resembles the baby cat attitude spoken of by Ramakrishna, is difficult to have. Those who are accustomed to a very active movement of their thought and will in all they do, find it difficult to still the activity and adopt the quietude of mental self-giving. This does not mean that they cannot do the Yoga or cannot arrive at self-giving—only the purification and the self-giving take a long time to accomplish and one must have the patience and steady perseverance and resolution to go through. <ref>http://incarnateword.in/cwsa/29/surrender#p78</ref>
