सूत्रार्थो वर्ण्यते यत्र वाक्यैः सुत्रानुसारिभिः ।
स्वपदानि च वर्ण्यन्ते भाष्यं भाष्यविदो विदुः ॥
sūtrārtho varṇyate yatra vākyaiḥ sutrānusāribhiḥ |
svapadāni ca varṇyante bhāṣyaṁ bhāṣya-vido viduḥ ||
(Abhiyuktokti)
“Knowers of a bhāṣya know a bhāṣya [i.e., a commentary] to be that in which the meaning of sūtras is explained with sentences that follow the sūtras and in which the sūtras’ own words are explained.”
