## Chapter of the Sevenfold Text (Sapttatika Prakarana)
120
Having explained the destruction of the Udayavikalpas and Prakritivikalpas through the various opinions, we now discuss the time duration of the Udayasthanas.
The lowest duration of the ten Udayasthanas and their destructions is one Samaya, and the highest duration is Antarmuhurta.
From the fourth Prakritik Udayastana to the tenth Prakritik Udayastana, the emergence of one Veda and one Yugal occurs in each Udayastana. The Veda and Yugal inevitably change within one Muhurta. This is also explained in the original commentary of the Panchasagraha:
"Ovem Yugalen Va Avashyam Muhurtabaras: Paravartitavyaam."
This means that the change of one Veda and one Yugal occurs within one Muhurta.
This confirms that the highest duration of these four Prakritik Udayasthanas and their destructions, which is stated as Antarmuhurta, is correct. The second and first Prakritik Udayasthanas also exist for a maximum duration of Antarmuhurta. Therefore, their highest duration is also Antarmuhurta.
The lowest duration of all these Udayasthanas is one Samaya. This should be understood as follows: When a being resides in a particular Udayastana or its specific destruction for one Samaya and then dies or undergoes a change to another Gunastana, there is a difference in its Gunastana. The Bandhastana also changes, and according to the Gunastana, there is also a difference in its Udayastana and its destructions. Therefore, the lowest duration of all Udayasthanas and their destructions is one Samaya.
