（kusala-maha^-bhu^mika）. One of the six groups of mental functions outlined in the Abhidharmako/sa-bha^sya 俱舍论. The ten mental conditions for cultivation of goodness， which are faith， zeal， renunciation， conscience， shame， no desire， no dislike， no harm， calmness and self control. A general term for the mental function that necessarily arises together with all virtues. The characters 'great-good-ground' （dashandi 大善地） mean 'virtue' （shanxin 善心）， therefore the term means 'virtuous elements.'
