Note 2 — Glory to Him, the Blessed Saint, the All-Enlightened one.
F. L. (Frank Lee) Woodward translation
The Brahmins used to claim that a "twice-born" saint was blameless, whatever his bodiless actions might be. The Buddha here speaks mystically. Father is ignorance, Mother is craving; the two kings are the great heresies of non-causation and nihilism. The Kingdom and its subjects are the six organs of sense (mind being the sixth); and the six objects of sense (form, sound, sight, smell, taste, thoughts), conquest of all these brings liberation from embodied existence.
