The Bowl of Saki Commentary

Evil, being of the nature of shadow or darkness, destroys spiritual vision, and so blinds one to the beauty which was the purpose of creation. This condition should be called avidya, blindness or ignorance.

There is, however, a difference between one who has evil in the mind and evil in the heart. The average person who does not know or seek truth may be called evil in mind. This person is under the sway of sin, as the Christians explain and has been demonstrated. But there is another sort of person called diabolical, who may be mentally alert but who has deliberately turned the heart into a charnel house, a hidden chamber where evil is planned to be committed in the world. These people can put wicked thoughts into the minds of others and can command evil elementals to influence others so that they may never perform any particular vile act directly.

This shows that all evil thought, desire, or speech may be responsible for the wrong acts of others. In this there is universal Karma, which was the explanation of the Buddha. So long as anybody sows Karma, it prevents others from being delivered from pain, disease, injury, and death.
