[375] Gladdening (sampahaṃsanā) is the ending (pariyosāna) of the first jhāna. How many characteristics has the ending?
The ending has four characteristics: gladdening in the sense that the dhammas arisen therein do not exceed one another; gladdening in the sense that the faculties (indriya) have a single function (ekarasa); gladdening in the sense of carrying the energy appropriate thereto; and gladdening in the sense of cultivation (āsevana). Gladdening is the ending of the first jhāna; these are the four characteristics of the ending. Therefore it is said that the first jhāna is beautiful in its ending and endowed with the characteristics. Thus the mind (citta) that has arrived at the threefold course, beautiful in three ways and endowed with the ten characteristics, is endowed with thought-conception (vitakka), endowed with discursive thought (vicāra), endowed with rapture, endowed with pleasure (sukha), endowed with steadiness of mind (cittassa adhiṭṭhāna), endowed with faith (saddhā), endowed with energy, endowed with mindfulness, endowed with concentration (samādhi), and endowed with wisdom (paññā).
