BG 14.4-6
In whatsoever wombs mortals are produced, O Kaunteya, the great Eternal is their womb, I their generating father. Harmony, Motion, Inertia, such are the qualities, Matter-born; they bind fast in the body, O great-armed one, the indestructible dweller in the body. Of these Harmony from its stainlessness, luminous and healthy, bindeth by the attachment to bliss and the attachment to wisdom, O sinless one.
