And what watery (liquid) fire, and what fragrance there was, that flowed together and burst forth from the eye, and became that tree, the pîtudâru; whence that (wood) is sweet-smelling, since it originated from fragrance, and whence it is inflammable, since it originated from fire: with that quality he thus endows it. And because these two (pîtudâru stakes) are on the two sides of the central one, therefore these two eyes are on the two sides of the nose: he thus puts those two in their own place.
