Sensitivity

Sensitivity means being sensitive to everything around one -- to the plants, the animals, the trees, the skies, the waters of the river, the bird on the wing; and also the moods of the people around one, and to the stranger who passes by. This sensitivity brings about the quality of uncalculated, unselfish, response, which is true morality and conduct.

Life Ahead, Krishnamurti

Buddhist tradition has identified this virtue as compassion, the origin of which is in mindfulness. Krishnamurti points to it as a methodology for dispelling the arbitrariness of culture and authority. Other traditions will root this virtue in metaphysics or define it as the essence of morality. But from the point of view of Krishnamurti's philosophy and psychology -- not Western but not merely Eastern, either -- mindfulness or sensitivity is a prerequisite to knowledge of self.
