[540] How does one develop serenity (samatha) and insight (vipassanā) yoked together (yuganaddha) in the sense of peace? When one is abandoning restlessness (uddhacca), the one-pointedness of mind (citta), the non-distraction, which is concentration (samādhi), is peaceful, having cessation (nirodha) as its domain; when one is abandoning ignorance (avijjā), insight, in the sense of contemplation, is peaceful, having cessation as its domain. Thus, in the sense of peace, serenity and insight are of a single taste, are yoked together, and do not overstep one another. Therefore it is said: one develops serenity and insight yoked together in the sense of peace.
How does one develop serenity and insight yoked together in the sense of sublimity? When one is abandoning restlessness, the one-pointedness of mind, the non-distraction, which is concentration, is sublime, having cessation as its domain; when one is abandoning ignorance, insight, in the sense of contemplation, is sublime, having cessation as its domain. Thus, in the sense of sublimity, serenity and insight are of a single taste, are yoked together, and do not overstep one another. Therefore it is said: one develops serenity and insight yoked together in the sense of sublimity.
How does one develop serenity and insight yoked together in the sense of liberation? When one is abandoning restlessness, the one-pointedness of mind, the non-distraction, which is concentration, is liberated, having cessation as its domain; when one is abandoning ignorance, insight, in the sense of contemplation, is liberated, having cessation as its domain. Thus, through the fading away of lust there is liberation of mind (cetovimutti); through the fading away of ignorance there is liberation by wisdom (paññāvimutti). Thus, in the sense of liberation, serenity and insight are of a single taste, are yoked together, and do not overstep one another. Therefore it is said: one develops serenity and insight yoked together in the sense of liberation.
