From Bhikkhu Bodhi's notes on the Chariot simile. Spk:
The eightfold path is called the straight way
) because it is devoid of crookedness of bodily conduct, etc. The destination, Nibbana, is said to be fearless
) because there is nothing to fear in that and because there is no fear for one who has attained it. Unlike an actual chariot, which rattles or whines when its axle is not lubricated or when it is mounted by too many people, the eightfold path does not rattle or whine. (na kujati na viravati
) even when mounted simultaneously by 84,000 beings. The chariot itself is also the eightfold path, and its wheels of wholesome states
) are bodily and mental energy. the D'hamma" that is called the charioteer
is the supramundane path, with the right view
of insight (vipassana-sammaditthi
) running out in front
). For just as the king's servants first clear the path before the king comes out, so the right view of insight clears the way by contemplating the aggregates, etc, as impermanent, etcd, and the right view of the path (magga-samma-ditthi
) arises fully understanding the round of existence.
The extended simile should be compared with that of the brahmayana
, the divine vehicle, at SN 45.4; see too the extended chariot simile at Ja VI 252-53.
SN 45.4 is at: http://www.metta.lk/tipitaka/2Sutta-Pit ... ggo-e.html44. 1. 4. (4) Bràhmano
(The numbering system is different in that translation from Bhikkhu Bodhi's).
