Muditā (Pāli and Sanskrit: मुदिता) is a dharmic concept of joy, particularly an especially sympathetic or vicarious joy—the pleasure that comes from delighting in other people's well-being.
[1] The traditional paradigmatic example of this mind-state is the attitude of a parent observing a growing child's accomplishments and successes.
The Buddha described this variety of meditation in this way: Here, O, Monks, a disciple lets his mind pervade one quarter of the world with thoughts of unselfish joy, and so the second, and so the third, and so the fourth.
And thus the whole wide world, above, below, around, everywhere and equally, he continues to pervade with a heart of unselfish joy, abundant, grown great, measureless, without hostility or ill-will.
[5] According to Buddhist teacher Ayya Khema showing joy towards sadistic pleasure[clarification needed] is wrong.
