When muc has an Intransitive signification guṇa is optionally substituted for its vowel before the aniṭ san of the Desiderative.,
By 1.2.10, after a root ending in a consonant, the सन् is like कित् and does not cause Guna. The present sutra ordains it optionally. As मोक्षते or मुमुक्षते वत्सः स्वयमेव ॥ In the Transitive there is one form only, as मुमुक्षति वत्सं देवदत्तः ॥ मुच् becomes Intransitive when it has a Reflexive significance, or when it expresses a mere action. The reduplication is elided by 7.4.58.,
