B.G 5.06

संन्यासस्तु महाबाहो दुःखमाप्तुमयोगतः। योगयुक्तो मुनिर्ब्रह्म न चिरेणाधिगच्छति ॥६॥

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.

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

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:

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

-states Padma Purana.

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:

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

-states testimonial.

Gīta Tātparya 5.06

Yōga is performing the activities without expectation and offering the results to lord Vishnu. Mere renunciation in the form of abandoning activities results in misery.

"The solution to liberation is Yōga. Its form only is renunciation. That which is offered to lord Vishnu is auspicious and considered as renunciation. There is no other way to renounce."

- states Agni Purana.

Only those activities performed as an offering to lord Vishnu is of the form of Yōga. Without such an attitude, if one renounces just the activities, it only results in misery.

"That which is termed as renunciation, understand it to be Yōga as well." (Gīta 6.2)

- it is stated thus in the future. Because of the speciality of Yōga, compared to mere renunciation, it is separately mentioned.
