That Breath created the Eye. This Eye, when created, wished to become manifest,--more defined, more substantial: it sought after a self. It practised austerity: it acquired consistency. It beheld thirty-six thousand Arka-fires of its own self, composed of the eye, built up of the eye: by means of the eye they were established, and by means of the eye built up; by the eye the cups were drawn thereat; by means of the eye they chanted and recited hymns on them,--whatever rite is performed as the sacrifice, whatever sacrificial rite there is, that was performed by the eye alone, as an eye-performance, on those (fires) composed of eye, and built up of the eye. And whatever beings here see with the eye that was done regarding those (fires):they establish them and build them up; they draw the cups for them; they chant on them and recite hymns on them,--of that extent was the development of the Eye, of that extent its creation,--so great is the Eye: thirty-six thousand Arka-fires; and each of these as great as that former (fire-altar) was.
