Good is that which elevates the mind and evil is that which degrades the mind. Social virtue and vice are temporal entities; they have nothing to do with your relationship with the Supreme.
The very strength that protects the heart from injury is the strength that prevents the heart from enlarging to its intended greatness within. The song of the voice is sweet, but the song of the heart is the pure voice of heaven.
The mind is the instrument, the flywheel, and the thickest comrade of man. Through it, one can ruin oneself or save oneself. Regulated and controlled, channeled properly it can liberate; wayward and let loose, it can entangle and bind fast.
The very nature of kindness is to spread. If you are kind to others, today they will be kind to you, and tomorrow to somebody else.
