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