[441] Which phenomena (dhammā) are indeterminate (abyākata)?
On the occasion when one develops supramundane (lokuttara) jhāna — leading out [of the round] (niyyānika), tending to the dismantling [of rebirth] (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 (dukkhāpaṭipadaṃ dandhābhiññaṃ), desireless (appaṇihita) — 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 upon and dwells in the first jhāna, of painful practice and sluggish direct knowledge, signless (animitta) — on that occasion there is contact … there is non-distraction … These phenomena are indeterminate.
