[448] Which phenomena (dhammā) are indeterminate (abyākata)?
On the occasion when one develops supramundane (lokuttara) jhāna — leading out (of the round) (niyyānika), conducing to the dismantling (of the round) (apacayagāmī) — for the abandoning of views (diṭṭhigata), for the attainment of the first plane (bhūmi): quite secluded from sensual pleasures … one enters upon and dwells in the first jhāna, of painful practice and sluggish direct knowledge (dukkhāpaṭipada dandhābhiñña), with zeal as the dominant factor (chandādhipateyya) — on that occasion there is contact (phassa) … there is non-distraction (avikkhepa) … These phenomena are wholesome.
Because that same supramundane wholesome jhāna has been done, has been developed, as its result (vipāka): quite secluded from sensual pleasures … one enters upon and dwells in the first jhāna — of painful practice and sluggish direct knowledge, desireless (appaṇihita), with zeal as the dominant factor — on that occasion there is contact … there is non-distraction … These phenomena are indeterminate.
