When the Buddha previously had explained to the Venerable Ānanda in respect to yāna, yāna was explained as a vehicle that travels on the wheels of wholesomeness: – dhammacakkehi saṃyuto.
(see 2.1.7): “Anyone who uses such a vehicle, be it woman or man, by means of it will get drawn close towards nibbāna.”–“Yassa etādisaṃ yānaṃ, itthiyā purisassa vā; sa ve etena yānena, nibbānasseva santike”ti.–
Here Jāṇussoṇi embarks the city of Sāvatthi in a superb vehicle that people compare with the divine vehicle of Brahma: ‘brahmayānaṃ’. After seeing this, the Venerable Ānanda questions the Buddha, if there was something that could be called a divine vehicle of Dhamma, the ‘dhammayāna’. The Buddha replies that this divine vehicle of Dhamma is the ‘dhammayāna’, the vehicle ‘yāna’ of the ariyassa aṭṭhaṅgikassa maggassa, by pointing out this maggayāna concluding with the following verse:
Niyyanti  lokamhā, aññadatthu jayaṃ jayanti.
That incomparable Brahma-like vehicle is produced from within,
Leading the wise away from the world, truly ever victorious.
 sambhūta: (pp) arisen, produced
 niyyanti: they are led (pp. of nāyati))
 aññadatthu: certainly, truly
 Jayaṃ jayanti rāgādayo sapatte jinantā jinantā: They win victory by overcoming and conquering the enemy of craving
 purisakāraṃ: purisa + kāra: man + deed, act, making
 nissāya: dependent upon; by reason of, through
