The life, of every man, is like a horse. The nature of that horse unmanifest. The elements from its body. Its nature is highly subtile. Kshanas, and Trutis, and Nimeshas are the hair on its body. The twilight's form its shoulderjoints. The lighted and the dark fortnights form its two equally powerful eyes. Months are its other limbs. That horse is running incessantly.
