[134] Regarding the *Urapasarpastri* and *Bhujapasarpastri*, one should say like a water creature. The *Khechari* can remain as a *Khecharastri* for an immeasurable fraction of a *Palyopam* time, from the lowest *Antarmuhurta* to the highest *Purvakotiprithaktva*.
**Discussion:** This sutra states the time duration for a *Tiriyachstri* to remain as a *Tiriyachstri*. A *Tiriyachstri* can remain as a *Tiriyachstri* from the lowest *Antarmuhurta* time to the highest *Purvakotiprithaktva* time, which is three *Palyopamas*.
The meaning of this is as follows: If a *Tiriyachstri* has a lifespan of only *Antarmuhurta* and dies, attaining *Vedantar* or a unique state like a human, then the lowest state duration of *Antarmuhurta* is appropriate.
The meaning of the highest state duration is as follows: A human and a *Tiriyach* can continuously experience eight births in the same form, but not more. Out of these, seven births have a lifespan of countable years, and the eighth birth has a lifespan of immeasurable years.
If a sufficient human or a sufficient sentient five-sense *Tiriyach* continuously experiences seven births of sufficient humans or seven births of sufficient sentient five-sense *Tiriyach*, and is born again in the eighth birth as a sufficient human or a sufficient sentient five-sense *Tiriyach*, then according to the rule, it has an immeasurable lifespan, not a countable lifespan.
A being with an immeasurable lifespan, upon death, is usually born in the *Devaloka*. Therefore, the ninth birth is not usually that of a human or a sentient five-sense *Tiriyach*.
Therefore, when the previous seven births are of the highest *Purvakoti* lifespan, and the eighth birth is in *Devakuru* etc., for three *Palyopamas* at the highest, then the duration of the *Tiriyastri* is three *Palyopamas* more than *Purvakotiprithaktva*.
In particular, a water creature female can continuously remain as a water creature female from the lowest *Antarmuhurta* to the highest *Purvakotiprithaktva*. After experiencing seven births of a water creature with a *Purvakoti* lifespan, there is definitely a change in the birth of a water creature.
The statement regarding a four-legged land creature is similar to that of a *Tiriyachstri*. That is, from the lowest *Antarmuhurta* to the highest *Purvakotiprithaktva*, it is three *Palyopamas*.
The statement regarding the *Urapasarpastri* and *Bhujapasarpastri* is according to the statement regarding the water creature female. That is, from the lowest *Antarmuhurta* to the highest *Purvakotiprithaktva*.
The duration of the *Khecharastri* is an immeasurable fraction of a *Palyopam* time, from the lowest *Antarmuhurta* to the highest *Purvakotiprithaktva*.
Thus, the duration of the *Tiriyachstri* has been stated in general and specific terms. The duration of the human female is similar.
