B.G 5.06

saṁnyāsastu mahābāho duḥkhamāptumaYōgataḥ। Yōgayukto munirbrahma na cireṇādhigacchati ॥6॥

O Arjuna, mere renunciation without being engaged in Yōga results in misery. The monk who is engaged in Yōga attains that Brahman, the supreme reality without delay.

Gīta Bhāshya 5.06

Yōga is superior to mere renunciation. Thus, when one combines renunciation with Yōga, it yields the ultimate good, hence become 'yōgayukto'. 'muni' - one who has given up desire and anger.

itaśca saṁnyāsād yogo varaḥ ityāha - saṁnyāsastu iti।

The 'saṁnyāsastu' verse conveys that Yōga is superior to mere renunciation.

yogābhāve mokṣādiphalaṁ na bhavati। ataḥ kāmajayādi duḥkhameva tasya। mokṣādyeva hi phalaṁ।anyat phalam alpatvāt aphalameva iti āśayaḥ। taccoktaṁ

In the absence of Yōga, one does not obtain liberation and such results. Thus, conquering desire and others (senses) will only result in misery. The intended meaning is - Only the liberation is considered as a result, as in comparison to liberation, everything else, being inferior, is like non-result. Therefore, it is said:

"vinā mokṣaphalaṁ yattu na tatphalamudīryate।"

"Whatever is without the fruit of liberation, that is not considered as a result."

iti pādme।

-states Padma Purana.

yattu mahatphalayogyaṁ tasya phalaṁ phalameva na bhavati। yathā padmarāgasya taṇḍulamuṣṭiḥ। mahāphalaśca Yōgayuktaścet saṁnyāsa ityāha - Yōgayukta iti। muniḥ saṁnyāsī। tathācoktam

A fist full of rice is not considered valuable compared to a precious ruby stone. Similarly, compared to whatever is capable of yielding great results, the miner results are considered as no result. When the renunciation is combined with Yōga, the greatest of results is possible. Hence it is told - 'Yōgayukta', i.e. engage yourself in Yōga. The word 'muni' means ascetic. Thus it is said:

"sa hi loke munirnāma yaḥ kāmakrodhavarjitaḥ।"

"Indeed, in this world he is called 'muni', i.e. monk, who has given up desire and anger."
