1. Samādhi Sutta.– One who is concentrated is one who knows as it really is the arising of the body and the passing away thereof; the same with feeling, perception, activities and consciousness. S.iii.13; cf. S.v.414; on this sutta see Sylvain Levi, JA.1908, xii.102.
2. Samādhi Sutta.– Develop concentration, monks. One who is concentrated sees things as they really are. The eye and forms, and feelings arising from eye-contact are impermanent. The ear and sound .. the tongue and flavours … the nose and odours … the body and contacts … the mind and ideas, and feelings arising from mental contact are impermanent. S.iv.80.
3. Samādhi Sutta.– There are three kinds of feelings: pleasant, unpleasant, and neutral. A monk who is concentrated and mindful understands them as they really are. S.iv.204.
4. Samādhi Sutta.– Right concentration with its supports and accessories: means right view, right thought, right action, right speech, right livelihood, right effort, and right mindfulness. S.v.21.
5. Samādhi Sutta.– Develop concentration, monks. One who is concentrated sees things as they really are. He sees, “This is suffering, this is the arising of suffering, this is the cessation of suffering, this is the way leading to the cessation of suffering. S.v.413.

12. Samādhi Sutta.– The Buddha explains how a monk who has won such concentration as to be unaware of earth, water, etc., yet contrives to have perception. A.v.7 f; cf. A.v.353 f.
