The eye sees all, but the mind shows us what we want to see.

More than those who hate you, more than all your enemies, an undisciplined mind does greater harm.

The practice of patience guards us against losing our presence of mind. It enables us to remain undisturbed, even when the situation is really difficult. It gives us a certain amount of inner peace, which allows us some self-control, so that we can choose to respond to situations in an appropriate and compassionate manner, rather than being driven by our disturbing emotions.

Be devoted to conscientiousness. Guard your own mind.

A positive state of mind is not merely good for you, it benefits everyone with whom you come into contact, literally changing the world.

Let us consider, first, the need for a tough mind, characterized by incisive thinking, realistic appraisal, and decisive judgment. The tough mind is sharp and penetrating, breaking through the crust of legends and myths and sifting the true from the false.
