That row of karmic substance, which is produced through the operation of Udīraṇā (bringing the Karma into the state of Udaya (rise) prematurely);
the Karmas which have entered into the āvalikā (the row) of Udīraṇā through the operation of Udīraṇā, but yet not have reached the state of Udaya (rise).
udiraṇākaraṇenākṛṣyodiraṇāvalikāṃ prāptā yāvadadyāpyndayaṃ na gacchanti.
