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.

Gīta Tātparya 6.01

The method of meditation is explained exclusively in this chapter. The ascetics are not without sacrificial fire. Indeed, they are offering their own self as a sacrifice.

॥hariḥ oṁ॥

Lord Hari oonly is Om!

dhyānamatrocyate।

The method of meditation is explained exclusively.

"sa brahmaniṣṭhastu yatirmahātmā śārīramagniṁca mukhe juhoti।"

"The great ascetic who is established in Brahman offers into the sacrificial fire of the body through his mouth." (For an ascetic, his body itself in the sacrificial fire, and food he eats through his mouth is like a sacrificial offering.)

ityādeḥ na yaterapi anagnitvam। ātmasamāropaṇācca ॥1॥

Such testimonials indicate that ascetics are not without sacrificial fire. Indeed, they are offering their own self as a sacrifice.
