This is in the scripture Brihadaaranyaka Upanishad. In the same sense, the true reality is covered up for man even in his waking state, state Kaarikas 4-6 of Chapter Two, because, translates Potter, "any object nonexistent in the beginning and in the end is also nonexistent in the middle". When we sleep, we feel the external things we dream about are real and the internal states as unreal, but in the awakened state we realize both are unreal. In the same way, in our waking state whatever we apprehend to be real and unreal are both unreal, covering up the true reality, state Kaarikas 10–15. But this assertion leads to the obvious question, states Gaudapaada, that if both internal and external are not true reality, who is it that imagines, who apprehends them and who cognizes? Gaudapaada submits his answer as the Aatman (Self, soul). "Gaudapaada Kaarika" states that while we do grasp objects, we perceive, we think, but this does not connote the nature of reality and unreality, just like our fear of "a rope for a serpent in darkness". We construct realities, states Gaudapaada, and imagine "Jivatman" to be various things such as "praana" (breath), "loka" (world), "deva" (gods), "bhoktr" (enjoyer), "bhojya" (enjoyables), "sukshma" (subtle), "sthula" (gross), "murta" (material), "amurta" (nonmaterial) and so on. We imagine things in our mind, we create things in our mind, we destroy things in our mind, says Gaudapaada; yet all these things are not different from It, the Aatman (gender neutral). All such constructions create dualities in our imagination, are Maaya. The true reality, state Kaarikas 33–36, is nondual and it is Aatman. Those who have mastered and grown past all attachments, past all fear and past all anger, they are past all dualities, know their Self, have secured the nonduality within. According to Kaarikas 36–38, such wise individuals, do not care about praise from anyone, are beyond all rituals, are homeless wanderers, for they have realized the true inside them and outside; they, translates Potter, "remain steadfastly true to nature".
