Purity is a state of mind in which we have no selfish or judgmental thoughts, no thoughts of like or dislike, or of pride, greed, or anger. It is the mindful state of mind in which we are no longer moving erratically between feelings of great happiness to those of discomfort or sadness. It is achieved when our minds are serene and stable, when our thoughts are of benefiting others, and when we are contented and are able to remain calm and at ease with everything we encounter.
