"There are, O monks, these three feelings: pleasant feelings, painful feelings, and neither-painful-nor-pleasant feelings."

A disciple of the Buddha, mindful, clearly comprehending, with his mind collected, he knows the feelings[1] and their origin,[2] knows whereby they cease[3] and knows the path that to the ending of feelings lead.[4] And when the end of feelings he has reached, such a monk, his thirsting quenched, attains Nibbana."[5]
