Improper thoughts and emotions such as those of violence – whether done, caused to be done, or even approved of – indeed, any thought originating in desire, anger or delusion, whether mild, medium or intense – do all result in endless pain and misery.
Overcome such distractions by pondering on the opposites.
When one is confirmed in non-violence, hostility ceases in his presence.
When one is firmly established in speaking truth, the fruits of action become subservient to him.
All jewels approach him who is confirmed in honesty…
When one is confirmed in non-possessiveness, the knowledge of the why and how of existence is attained…
As a result of contentment there is purity of mind, one-pointedness, control of the senses, and fitness for the vision of the self.
Supreme happiness is gained via contentment.
Through sanctification and the removal of impurities, there arise special powers in the body and senses.
By study comes communion with the Lord in the Form most admired.
Realization is experienced by making the Lord the motive of all actions.
