## The Study of the Samvasarana
**The Sorrow** is the arising of the non-existent, and its cause, whoever knows, and **the Happiness** which is the opposite of that, whoever knows, by penance, whoever is purified, this is said - whoever knows the causes of the bondage of karma and the causes of its opposite equally, thus:
"As many are the types, the causes of the bondage of the world, so many are the opposites of those, the causes of the liberation of Nirvana." ||1||
He alone truly deserves to speak, what is that? He says - the **Action-Theory**, that there is a soul, there is merit, there is sin, and there is the fruit of past actions, such a theory. Thus - the soul, non-soul, restraint of inflow, bondage, merit, sin, purification, liberation - these nine substances are included in two verses. There, by "whoever knows himself", the substance of the soul is understood, by "world", the substance of the soul is understood, and by "going, not going, eternal, etc.", the nature of these two is shown. Similarly, inflow and restraint are included in their own form. By "sorrow", however, bondage, merit, and sin are taken, because sorrow is inseparable from them. Purification, however, is not included in its own definition, but the fruit of that, liberation, should be understood. Thus, these are the substances, and by accepting them, the Action-Theory is accepted.
Whoever "knows", accepts, he truly knows the Action-Theory. But, is the rightness of the theory not established by the knowledge of the substances mentioned by other schools? Why is it not accepted? Because the names of the substances mentioned are not established. Thus, in the Nyaya school, sixteen substances are mentioned - **proof, object of proof, doubt, purpose, example, principle, constituent, reasoning, determination, debate, quibbling, fallacy, deception, category, refutation, and position**. There, the **object of proof** is that by which the delimitation of the substance is done, in the form of **avoidance** and **acceptance** (restraint and activity). And that is **proof**, which is of four types - **perception, inference, comparison, and verbal testimony**. There, the knowledge arising from the contact of the sense organ with the object is **perception**, which is **unnameable**, **invariable**, and **determinative**. That is, the knowledge arising from the relation between the sense organ and the object, not the manifested knowledge, not happiness, etc., is **unnameable**, because it is nameable by verbal testimony; and because it is **invariable**, it is not variable like the knowledge of two moons. **Determinative** means that it is **certain**. There, its perceptibility is not appropriate, because where the self is directly present for the grasping of the object, that is perception. And that is only **attention**, **mind**, and **self**. And this is also through another **condition**. Inference is **indirect** like the inference of activity. **Conventional perception** may be there, but convention is not relevant in the investigation of truth. Inference is also of three types - **from the cause**, **from the effect**, and **from the general**. There, **inference from the cause** is like the previous, **inference from the effect** is like the remainder, and **inference from the general** is like seeing a single blooming flower and concluding that all flowers are blooming, or seeing the movement of Devadatta from one place to another and inferring movement in the sun. There, also, **incompatibility** is the means of inference, not the cause, etc., because without it, there is variability in the relation between the cause and the effect. Where it exists, there, the relation between the cause and the effect, etc., is seen as the inferred and the means of inference. For example, "There will be a chariot rising from the sight of the constellation Krittika." It is said:
"Incompatibility, where it is, what is the use of the three? Incompatibility, where it is, what is the use of the three?" ||1||
Moreover, if perception is not authoritative, then inference preceding it is authoritative. **Comparison** is the well-known means of proving the object to be proved, like "A cow is like a bull." Here, the meaning of comparison is the understanding of the relation between the similar and the dissimilar. Here, also, it is established that it is a type of inference, because it is included in the established incompatibility, and therefore, its separate authority is not established. If there is no incompatibility, then there is variability, and therefore, comparison is not authoritative. **Verbal testimony** is also not all authoritative. What then? Only the **scripture** composed by the **knowledgeable** is authoritative. And it is not reasonable that there is another knowledgeable person besides the omniscient. This is also discussed elsewhere. Further, all this proof is the knowledge of the self, and knowledge is a quality of the self. If it is a separate substance, then there is a contradiction. If they are dependent on the sense organ and the object for the grasping of the object of proof, then they are dependent, but not reasonable. Thus, because they are absent without substance, and because their grasping is established in the grasping of that, it is not reasonable to accept them separately. The **object of proof**, however, is the self, body, sense organ, object, intellect, mind, activity, fault, death, absence, fruit, sorrow, and liberation. There, the self is the perceiver and enjoyer of all, and it is inferred from hatred, effort, happiness, sorrow, and knowledge. And it is accepted as the substance of the soul. The body is the place of its enjoyment, the sense organs are the instruments of enjoyment, and the objects of the sense organs are the objects of enjoyment. This body, etc., is also mentioned by us in the understanding of the soul and non-soul. Enjoyment is intellect, and this is a special type of knowledge. And it is accepted as a quality of the soul, and therefore, it is accepted as the soul.
