Always aim at complete harmony of thought and word and deed. Always aim at purifying your thoughts and everything will be well.

I will not let anyone walk through my mind with their dirty feet.

A spirit is not necessarily purer, because it is disembodied.

To a pure heart all hearts are pure.

Purification is never for the selfishly idle, it accrues only to the selflessly industrious.

Pure motives can never justify impure or violent action.
