It seems the suttas instruct us to establish mindfulness (sati) & clear-comprehension (sampajanna), which can manifest as concentration (samadhi), as follows:
However, the suttas also seem to instruct the "calming of breathing" ("passambhayaṃ kāyasaṅkhāraṃ"), as follows:Here a bhikkhu, gone to the forest or to the root of a tree or to an empty hut, sits down; having folded his legs crosswise, set his body erect, and established mindfulness in front of him.
My question for discussion is, if mindfulness, clear-comprehension & samadhi are established, where there are no major hindrances, why does breathing calm?He trains thus: ‘I shall breathe in tranquillising the kāyasaṅkhāraṃ’; he trains thus: ‘I shall breathe out tranquillising the kāyasaṅkhāraṃ.’
Even though mindfulness is established, why does breathing lack calmness so it must be calmed?
Thanks
