He alone is capable of removing from the heart of another doubt, deceit, fear or malice whose heart is already pure from these things or who, at least, can empty his heart of these things. There is a weakness of the heart and there is a strength of the heart. The heart's weakness is caused by things it contains which enfeeble it, such as doubt, deceit, fear and malice. The absence of these things produces that purity of heart which in itself is a power. This power could be increased by faith, hope and righteousness.

Purity of the heart causes its expansion and the lack of purity makes it narrow.

The mystic poet of Hyderabad, Asef, says, "If the heart is large, it can be largest of all things."

Besides, it is purity alone which opens the doors of the heart. All that hinders that purity stands as a closed door of the heart.

The pure-hearted may seem to be thinking, saying or doing simple things. And yet there is a beauty and charm in all they do, for there is nothing more attractive than light itself. All that is besides light depends upon the light to show out its beauty, light is beauty in itself. Purity of the heart is the only condition that allows the inner stream to rise. The pure-hearted see deeper, though they say little. There is no pretense about them. What they know they know; what they don't know they don't know.

The pure ones make all pure, for to them all is pure. Their presence makes everyone pure. As the pure water is the best tonic so is the contact of the pure hearted person. In the spiritual path when one is able to accomplish this thing there is not much then that remains to be accomplished.
