8.5.28

ajasya cakraṃ tvajayeryamāṇaṃ manomayaṃ pañcadaśāramāśu /
trinābhi vidyuccalamaṣṭanemi yadakṣamāhustamṛtaṃ prapadye //

28. “I resort to that Truth (the supreme Being) which, the wise say, is the axle (the main support) of the wheel of life, (comprising the body and other environments of the soul), set in motion (set to work) by Maya, with the mind for its chief member, provided with fifteen spokes, and with the nave constituted of three gunas and fickle and transient like lightning and also furnished with eight fellies (eight tires) _viz._, eight forms of Prakriti.
