One is truly perfectly pure only when the whole being, in all its elements and all its movements, adheres fully, exclusively, to the divine Will. This indeed is total purity. It does not depend on any moral or social law, any mental convention of any kind. It depends exclusively on this: when all the elements and all the movements of the being adhere exclusively and totally to the divine Will…
As soon as you speak of purity, a moral monument comes in front of you which completely falsifies your notion. And note that it is infinitely easier to be moral from the social point of view than to be moral from the spiritual point of view. To be moral from the social viewpoint one has only to pay good attention to do nothing which is not approved of by others; this may be somewhat difficult, but still it is not impossible; and one may be, as I said, a monument of insincerity and impurity while doing this; whereas to be pure from the spiritual point of view means a vigilance, a consciousness, a sincerity that stand all tests.
