Karika 79 states that if only the knowledge principle exists and no external meaning, then all intellects and all statements would be false, because the validity of both depends on external meaning. Those whose known external meaning is true are called evidence, and those whose meaning is not true are called apparent evidence. But in the theory of knowledge-only, because external meaning is not accepted, the certainty of any intellect and any statement cannot be determined, and therefore they will be called false. And when they are false, they are included in the category of apparent evidence. But how can they be called apparent evidence without evidence? The implication is that if only the knowledge principle is accepted, then neither evidence nor apparent evidence is formed. And if they are not formed, how can knowledge alone be proved real and external meaning unreal?
Karika 80 shows the futility of trying to prove the principle of knowledge-only through the understanding of the object and the means, because such a proof leads to the fault of the proposition and the fault of the reason. It is clear that those who believe in the principle of knowledge-only have neither the object nor the reason. Otherwise, the consequence of duality would arise.
Karika 81 criticizes those who accept only external meaning and do not accept internal meaning (knowledge). It is said that if only external meaning exists and no knowledge, then there will be no doubt, no error, and no indecision. Not only that, the determination of truth and falsehood will also not be possible. Consequently, even those who advocate the opposite meaning will achieve their goals of liberation, etc. In addition, because dream intellects are not connected with self-interest, they cannot be called non-convincing.
Karika 82 shows the fault of complete dualism in the contradiction and the fault of complete non-dualism in the inability to express it with the word 'non-dual'.
Karika 83 shows that there is no fault in arranging the reality of things through Syadvada, saying that there is no need for a perception of the nature of things, because...
