Verse 2.54

Sanskrit text and transliteration:

निरस्यति यथैवैकं तथैवान्यद्विरोधि यत् ।
स्वात्मनैवैकरूपेण लक्ष्यमत्र निगद्यते ॥ ५४ ॥

nirasyati yathaivaikaṃ tathaivānyadvirodhi yat |
svātmanaivaikarūpeṇa lakṣyamatra nigadyate || 54 ||

English translation of verse 2.54:

Here, the defined is said to be that which, through its definition which is one, is distinguished from other objects of its own class, as also of other classes which are opposed to it.

Notes:

A thing is said to be the defined (lakṣya) when it is marked off from all else by its definition (svalakṣaṇena sarvasmādvyāvartitaṃ yattallakṣyam).
