23. The pulsation of consciousness (citspanda) itself is manifested within the pulsation of consciousness, within the all-pervading Self (ātman). Both vibration (spanda) and non-vibration (aspanda), along with their manifestation (jṛmbhaṇa) and other aspects, are merely conceived here; they are not real (vāstava).
