## 102] Sarvarthasiddhi
[1133 8 244] The term "vyavahar" is used based on convention. Since it is not possible to use "vyavahar" for the collection of both jiva and ajiv, each is considered separately, such as dev, narak, etc. for jiva and ghata, etc. for ajiv. This principle applies until there is no further division possible.
[8 245] The principle of "Riju Sutra" means to accept what is straight or simple. This principle accepts only the objects of the present time, not the objects of the past or future. This is because the past is destroyed and the future is not yet born, so there is no "vyavahar" for them. The present time is just a moment, and this "Riju Sutra" principle deals only with the objects of that moment.
**Question:** Doesn't this lead to the disappearance of "vyavahar"?
**Answer:** No, because this principle only shows the object of the principle. "Vyavahar" is achieved by the collective effort of all principles.
[8 246] The principle of "Shabda Nay" aims to eliminate the errors in ling, sankhya, sadhan, etc.
**Ling Vyabhichar:** For example, "Pushya, Taraka, Nakshatra" are words with different lingas. Using them together is "Ling Vyabhichar".
**Sankhya Vyabhichar:** For example, "Jal, Apah, Varsha, Ritu, Amra, Van, Varana, Nagar" are words with singular and plural endings. Using them in a way that violates their singular/plural nature is "Sankhya Vyabhichar".
**Sadhan Vyabhichar:** For example, "Sena parvatam adhivasati" (The army resides on the mountain). Here, the seventh case ending (for the object of the preposition) is not used, but the second case ending is used, which is "Sadhan Vyabhichar".
**Purusha Vyabhichar:** For example, "Ehi manye rathena yasyasi, na hi yasyasi, yataste pita" (Come, you think I will go by chariot, you will not go, your father has gone). Here, "manyase" is replaced by "many" and "yasyami" is replaced by "yasyasi", which is "Purusha Vyabhichar".
**Kal Vyabhichar:** For example, "Vishvadrushva asya putro janita" (Vishvadrushva will be his son). Here, "Vishvadrushva" is used as the subject, and "janita" is used as the verb, which is "Kal Vyabhichar". Or, "Bhavikruti masit" (The future action has happened). Here, the future action is described as having happened, which is "Kal Vyabhichar".
