Doing good to others is virtue (Dharma); injuring others is sin.
Strength and manliness are virtue; weakness and cowardice are sin.
Independence is virtue; dependence is sin.
Loving others is virtue; hating others is sin.
Faith in God and in one’s own Self is virtue; doubt is sin.
Knowledge of oneness is virtue; seeing diversity is sin.
The different scriptures only show the means of attaining virtue.
— Swami Vivekananda, Complete Works, 5:419
