स्वभावोऽस्य भवेन्नित्यं न त्वाहार्यो गुणोऽस्य सः ॥ ५४ ॥

yathā himasya śītatvaṃ vahnerauṣṇyaṃ tathedṛśaḥ ,
svabhāvo'sya bhavennityaṃ na tvāhāryo guṇo'sya saḥ 54

svabhāvaḥ asya bhavet nityam na tu āhāryaḥ guṇaḥ asya saḥ

54. yathā himasya śītatvam vahneḥ auṣṇyam,
tathā īdṛśaḥ svabhāvaḥ asya nityam bhavet,
tu saḥ asya āhāryaḥ guṇaḥ na

54. Just as coldness is the intrinsic nature (svabhāva) of snow and heat is that of fire, similarly, this state of being is the eternal and intrinsic nature (svabhāva) of such a person; it is not an acquired attribute.
