The Gādhaṣṭisamuccaya is called the cycle of existence (bhava-saṃsāra). And since the eternality of existence is denied, how can liberation (mokṣa) be possible for the liberated one? Therefore, one must accept initiation (dīkṣā) and other causes. With initiation and the like, there is the cycle of existence, and in their absence, there is liberation. Thus, two states will be established.
(3) And he also says that this state is not from the essence (tattva), how will its cognition arise? What is the proof of this cognition being tranquil? Yogic knowledge (yogijñāna) is the proof, and that itself has become a different state. If he calls this knowledge erroneous (bhrānta), how did he first call it proof? And if he calls it non-erroneous (abhrānta), then you have accepted the opposite state. Thus, the absolute eternal aspect (bhāvarūpa vastu) is not established in any way.
The purport is that the substance (vastu) is of the nature of being and non-being, i.e., it is eternally transforming. If we accept this, then the entire system of saṃsāra and mokṣa is properly established, because the impurity (bhāvamala) and so on arise from the inherent nature (svabhāva), yet due to the connection with the root nature, they undergo transformation. This is the absence of hatred (adveṣapañā). And this inherent nature is the nature of the substance, i.e., it is its own essential being (sattā). The abiding in the inherent nature is liberation (mokṣa), that is the absence of hatred; and the abiding in the modified state is the cycle of existence (saṃsāra), that is the presence of hatred.
As a corollary, we are now discussing the nature (prakṛti), and that nature is the perfected form (siddhasvarūpa), as described through examples like the boastful ox freed from disease, etc. Therein:
व्याधितस्तदभावो वा तदन्यो वा यथैव हि । व्याधिमुक्तो न सन्नीत्या कदाचिदुपपद्यते ॥ २०४
The meaning is: The one afflicted by the disease, or its absence, or something else - just as the one freed from the disease is never established through proper reasoning.
The explanation is: The one afflicted by the disease, or its absence, or something else - such as a son, etc. - none of these three can ever be established as "freed from the disease" through proper reasoning.
