B.G 6.01

śrī bhagavānuvāca
anāśritaḥ karmaphalaṁ kāryaṁ karma karoti yaḥ। sa saṁnyāsī ca yogī ca na niragnirna cākriyaḥ ॥1॥

The revered Divine Lord said,
One who performs activities without seeking the fruits of the action is both a renunciant and a Yogi. Not he who is devoid of fire, as well as activities.

Gīta Bhāshya 6.01

An internal discipline to be practiced for knowledge is explained in this chapter. Practicing detachment is necessary along with Yoga. Intent is not to recommend detachment and inaction for monkhood.

॥hariḥ oṁ॥

Lord Hari is only Om!

jñānāntaraṅgaṁ samādhiyogam āha anena adhyāyena। vivakṣitaṁ saṁnyāsamāha yogena saha - anāśrita iti। caturthāśramiṇo'pi agniḥ kriyā ca uktā 'daivameva' ityādau।

In this chapter, the yoga of equanimity, which is an internal discipline to be practiced for knowledge, is expounded. The required detachment to be practiced along with Yoga is explained in 'anāśrita' verse. Even for those in the fourth stage of life, i.e. monkhood, the necessity of action and the concept of sacrificial fire have been explained in the verse 'daivameva' (Gita 4.25).

"agnirbrahma ca tatpūjā kriyā nyāsāśrame smr̥tā॥"

"For the renounced order, fire is the Brahman, and his worship is the recommended action."

iti ca।

- stated thus by testimonials as well.

tasmāt niragniḥ akriyaḥ saṁnyāsī yogī ca na bhavatyeva ॥1॥

Therefore, without sacrificial fire and without duties, one is neither an ascetic nor a Yogi.
