All feelings and emotions， whether good or bad， wholesome or evil， disturb the peacefulness of the mind， preventing one's innate wisdom from manifesting itself. Therefore， they should all be avoided equally. A person overcome by any kind of emotion is not on an even keel and may not exercise good judgment or do what has to be done. Thus， joy， too， is an affliction! （Note: The word "joy" used to describe life in the Pure Land of Amitabha Buddha is not the ordinary joy of this world but is rather the joy of "permanence， bliss， self and purity" -- the opposite of the Dharma seals （q.v.） of impermanence， suffering and no-self that characterize the Saha World）.
