As is said in the Upanishads, our whole mind-consciousness is shot through with the threads and currents of this Prana, this Life-energy that strives and limits, grasps and misses, desires and suffers, and only by its purification can we know and possess our real and eternal self. <ref>http://incarnateword.in/cwsa/23/the-release-from-the-heart-and-the-mind#p4</ref>
= Object of Purity =
The object of purification is to make the whole mental being a clear mirror in which the divine reality can be reflected, a clear vessel and an unobstructing channel into which the divine presence and through which the divine influence can be poured, a subtilised stuff which the divine nature can take possession of, new-shape and use to divine issues. For the mental being at present reflects only the confusions created by the mental and physical view of the world, is a channel only for the disorders of the ignorant lower nature and full of obstructions and impurities which prevent the higher from acting; therefore the whole shape of our being is deformed and imperfect, indocile to the highest influences and turned in its action to ignorant and inferior utilities. It reflects even the world falsely; it is incapable of reflecting the Divine. <ref> http://incarnateword.in/cwsa/23/the-higher-and-the-lower-knowledge#p6 </ref>
