Among innumerable beings, someone, who by great austerity has got rid of sins and has increased his merits, realises this self possessing the above mentioned nature, which is wonderful and distinct in kind from all things other than Itself. Such a one speaks of It to another. Thus, someone hears of It. And even after hearing of It, no one knows It exactly that It really exists. The term ‘ca’ (and) implies that even amongst the seers, the speakers and hearers, one with authentic perception, authentic speech and authentic hearing, is a rarity.
