The 29th and 30th * *Prajñāpanā Sūtra* discuss the *upayoga* and *paśyattā* of beings. The main characteristic of a being or soul is *upayoga*, and *paśyattā* is its main part. However, the soul is bound to the body. Due to the body, limbs, senses, mind, etc., are obtained. Every being, whether it is one-sensed, disabled, or five-sensed, a god, a hell being, a human, or a non-human, receives limbs, senses, etc., according to their karma. The soul of all beings is inherently knowledge-filled and perception-filled, as stated in the *Prācārāṅga Sūtra*: "What is the soul, that is the knower, and what is the knower, that is the soul. What is known, that is the soul." The question arises: If all souls are knowledge-perception-filled (*upayoga*-filled), formless, and eternal, as stated in the *Bhagavati Sūtra*: "The soul is without smell, without form, without taste, without touch, and without breath. It is eternal and pervades the entire universe. It is described in five ways: substance, space, time, nature, and qualities. The substance is infinite, the space is the size of the universe, the time is eternal, the nature is without form, and the qualities are *upayoga* qualities." Here, the nature of the soul is described in five ways. The substance is infinite, the space is the size of the universe, the time is eternal, the nature is without form, and the qualities are *upayoga* qualities. Therefore, even though all souls have the same qualities and *upayoga*, some have less *upayoga*, some have more, some have knowledge that pervades the three times and three worlds, and some have no knowledge or perception even of the present moment or a single inch of space. Why is this? 1. *Upayoga* is the characteristic - *Tattvārtha Sūtra* 2. *Prācārāṅga Sūtra* 1, 5, 5, 165 3. *Bhagavati Sūtra* 2, 10, 5 (Prā. Pr. Samiti)
