On Adhyatma Upanishad: Honestly watch your actions, and you’ll be liberated

The following excerpt is from a samvaad (dialogue) session with Acharya Prashant.

क्रियानाशाद्भवेच्चिन्तानाशोऽस्माद्वासनाक्षयः ।वासनाप्रक्षयो मोक्षः सा जीवन्मुक्तिरिष्यते ॥ १२॥

kriyānāśādbhaveccintānāśo’smādvāsanākṣayaḥ ।vāsanāprakṣayo mokṣaḥ sā jīvanmuktiriṣyate ॥ 12॥

The destruction of actions leads to that of thought; thence results the dwindling of innate impulses (to act). The obliteration of innate impulses is liberation; it is held to be freedom in life. || 12||

~ Adhyaatm Upanishad (Verse 12)

Questioner (Q): Acharya Ji, Pranaam! I am aware that I have innate impulses like anger, greed, pride, fear, and attachments. Kindly help me understand this process of dwindling of innate impulses, as mentioned in this verse.

Acharya Prashant (AP): It is the path, the method that proceeds from the gross and goes towards the subtle. This method is for those who cannot begin from the subtle-most.
