Passaddhi is identified as a wholesome factor in the following canonical contexts: In various Buddhist canonical schema, the calming of the body, speech and various mental factors is associated with gladness (pāmojja, pāmujja), rapture (pīti), and pleasure (sukhaṃ) and leads to the concentration needed for release from suffering.
Calming (passambhayaṃ) bodily and mental formations is the culmination of each of the first two tetrads of meditation instructions in the Pali Canon's famed Anapanasati Sutta: A number of discourses identify the concurrent arising of the following wholesome mental states with the development of mindfulness (sati) and the onset of the first jhana: By establishing mindfulness, one overcomes the Five Hindrances (pañca nīvaraṇi), gives rise to gladness, rapture, pleasure and tranquillizes the body (kāyo passambhati); such bodily tranquillity (passaddhakāyo) leads to higher states of concentration (samādhi) as indicated in this Pali-recorded discourse ascribed to the Buddha: Alternately, with right effort and sense-restraint, paññā ("wisdom," "discernment") is fully realized, and the jhana-factors arise: Passaddhi is the fifth of seven factors of enlightenment (sambojjhanga) that lead to deliverance from suffering.
Among the factors of enlightenment, serenity (passadhi) is preceded by rapture (pīti) and leads to concentration (samādhi) as further described by the Buddha in the Anapanasati Sutta: In describing one's progressive steps through the absorptions (jhanani), the Buddha identifies six sequential "calmings" (passaddhis): Passaddhi is a "supporting condition" for the "destruction of the cankers" (āsava-khaye), that is, the achievement of Arahantship.
More specifically, in describing a set of supporting conditions that move one from samsaric suffering (see Dependent Origination) to destruction of the cankers, the Buddha describes the following progression of conditions: In the Pali literature, this sequence that enables one to transcend worldly suffering is referred to as the "transcendental dependent arising" (lokuttara-paticcasamuppada).
In the Visuddhimagga, the enlightenment factors (bojjhangas) are discussed in the context of skills for developing absorption (jhāna).
