What, then, is the ultimate truth? The answer is that nondual knowledge is the ultimate truth. It is devoid of the contamination of material qualities. It gives us liberation. It is the one without a second, all-pervading and beyond imagination. The first realization of that knowledge is Brahman. Then Paramatma, the Supersoul, is realized by the yogis who try to see Him without grievance. This is the second stage of realization. Finally, full realization of the same supreme knowledge is realized in the Supreme Person. All learned scholars describe the Supreme Person as Vasudeva, the cause of Brahman, Paramatma and others.
