Sings Bhagavad Gita:

यस्य सर्वे समारम्भाः कामसंकल्पवर्जिताः ।
ज्ञानाग्निदग्धकर्माणं तमाहुः पण्डितं बुधाः ॥४-१९॥

yasya sarve samārambhāḥ
kāmasankalpavarjitāḥ,
jñānāgnidagdhakarmāṇam
tam āhuḥ paṇcitam budhāḥ (19)

“Even the learned call that man a sage all of whose actions are free from desire and will, (both) burnt to ashes by the fire of knowledge.’’

With the acquisition of the capacity of perceiving non-action in action, the man who is engaged in action grows into a doer of perfect action in which there is not even the slightest flaw.

Restraint of desire and will is a victory of the mind. So action is something that elevates the mind above desire and will.Sri Krishn tells Arjun that a well-commenced action gradually becomes so refined and sublimated that it takes the mind above will as well as irresolution and then, with the burning out of even the last desire which he does not know but which he was previously eager to know, the worshipper is blessed with direct perception of God.

Revered Gurudev

Direct knowledge of God by following the path of action is called knowledge (gyan): the sacred knowledge that enables the Soul to be united with the Supreme Spirit. The fire of this direct perception of God annihilates action for ever. What was sought has been achieved. There is nothing beyond it to quest for. Who is there beyond God to search for with further endeavour? So with the attainment of this wisdom, the need for action comes to an end. Rightly have sages called men with such wisdom pandit, men of profound erudition. Their learning is perfect.

Bhagavad Gita  further adds:

त्यक्त्वा कर्मफलासङ्गं नित्यतृप्तो निराश्रयः ।
कर्मण्यभिप्रवृत्तोऽपि नैव किंचित्करोति सः ॥४-२०॥

tyaktvā karmaphalāsaṇgam
nityatṛpto nirāśrayaḥ,
karmaṇy abhipravṛtto’pi
nai’va kimcit karoti saḥ (20)

‘‘Independent of the world, ever contented, and renouncing all attachment to action as well as its fruits, such a man is free from action even while he is engaged in it.”

Declining to rest upon objects of the world, utterly contented with dwelling in the eternal God, and discarding not only desire for the fruits of action but even attachment to God because now he is not removed from Him, this sage is a non-doer even while he is diligently employed in the performance of action.

As expounded by Swami Adgadanad Paramhans, most revered Gurudev.
