[433] Which phenomena (dhammā) are indeterminate (abyākata)?
On the occasion when one develops supramundane (lokuttara) jhāna—leading out (niyyānika), leading to dismantling (apacayagāmī)—for the abandonment of views (diṭṭhigata), for the attainment of the first plane (bhūmi): quite secluded from sensual pleasures … one enters and dwells in the first jhāna, of painful practice and sluggish direct knowledge (dukkhāpaṭipadā dandhābhiññā), emptiness (suññata); on that occasion there is contact (phassa) … there is non-distraction (avikkhepa) … These phenomena are wholesome.
As the result (vipāka) of that same supramundane wholesome jhāna—because it has been done, because it has been developed—quite secluded from sensual pleasures … one enters and dwells in the first jhāna, of painful practice and sluggish direct knowledge, desireless (appaṇihita); on that occasion there is contact … there is non-distraction … These phenomena are indeterminate.
