[461] Which phenomena (dhammā) are indeterminate (abyākata)?
On the occasion when one develops supramundane (lokuttara) jhāna — leading out (niyyānika), going to diminution (apacayagāmī) — for the abandonment of views (diṭṭhigata), for the attainment of the first stage (bhūmi): quite secluded from sensual pleasures … one enters and dwells in the first jhāna, undirected (appaṇihita), with zeal as the dominant influence (chandādhipateyya); 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's having been done, having been developed: quite secluded from sensual pleasures … one enters and dwells in the first jhāna, signless (animitta), with zeal as the dominant influence; on that occasion there is contact … there is non-distraction … These phenomena are indeterminate.
