Indeed, this heart has five divine apertures. That which faces the east is the breath; that is the eye, and that is the sun. Whoever meditates upon this shining light and food as such becomes radiant and an enjoyer of food.

Of this indeed heart there are five divine apertures. That which is its eastern aperture, that is the prana, and that is the eye, that is the sun. One should meditate on this very light and food as radiant and a consumer of food, who knows thus.
