ayam api yogaḥ śakyaḥ avaktum .

katham aham bravīmi , āvām brūvaḥ , vayam brūmaḥ .

imāni indriyāṇi kadā cit svātantryeṇa vivakṣitāni bhavanti .

tat yathā : idam me akṣi suṣṭhu paśyati .

ayam me karṇaḥ suṣṭhu śṛṇoti iti .

kadā cit pāratantryeṇa : anena akṣṇā suṣṭhu paśyāmi .

anena karṇena suṣṭhu śṛṇomi iti .

tat yadā svātantryeṇa vivakṣā tadā bahuvacanam bhaviṣyati .

yadā pāratantryeṇa tadā ekavacanadvivacane bhaviṣyataḥ .
