soul, all the prāṇas are considered to be senses.
Siddhānta (conclusion): In the following words the author of the sūtras gives
His conclusion.
Sūtra 17
ta indriyāṇi tad vyapadeśād anyatra śreṣṭhāt
te—they; indriyāṇi—senses; tat—that; vyapadeśāt—because of the description;
anyatra—otherwise; śreṣṭhāt—from the best.
They are senses, for that is the description. Only the principal one is not.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
With the sole exception of the principal prāṇa, the prāṇas are all senses. Why is
that? The sūtra explains: "For that is the description." In the Muṇḍaka Upaniṣad
(2.1.3) it is said:
etasmāj jāyate prāṇaḥ
manaḥ sarvendriyāṇi ca
"From the Supreme Personality of Godhead are born the principal prāṇa, the
mind, and the senses."
In this way, with the sole exception of the principal prāṇa, the prāṇas are the
senses, such as the ears and the others. In the Smṛti-śāstra it is said:
indriyāṇi daśaikaṁ ca
"There are eleven senses."
In another place in the Śruti-śāstra it is said:
prāṇo mukhya sa tv anindiriyam
