Dhāraṇā 108 · Where is knowledge, where is action
For a changeless Self, knowing and doing are impossible predicates; and since outer things hang on knowing, the world so conceived is void — an argument to be inhabited, not just followed.
This dhāraṇā is an argument — two steps of metaphysics compressed into a verse — and the practice is the strange discipline of living inside an argument until it stops being inference and becomes vista.
The two steps
Step one: of the Self that is nirvikāra, changeless, the verse asks — where is knowledge, and where action? Both are events; events are changes; a changeless reality can host neither. The rhetorical kva … kva does the work of a proof: there is simply no room in the changeless for an episode. Step two turns outward: jñānāyattā bahir-bhāvāḥ — external existents are dependent on knowledge. A thing's whole career, for you, is its being-known; subtract every act of cognition and nothing of ‘the outer’ remains standing on its own. Combine the steps: the world hangs on knowing, and knowing finds no purchase in what truly is. Ataḥ śūnyam idaṃ jagat — hence this world is void.
Inhabiting it
Run the argument slowly, with live examples, at the level of this hour. The room you are in: trace how its entire reality-for-you rides on present and remembered cognitions. Then the cognitions themselves: episodes, flickering, none of them findable in the still ground that is aware of them. Then rest as that ground and let both dependents — the knowing, and the world that leaned on the knowing — go quiet together. Done as mere philosophy the verse convinces for a minute; done as dhāraṇā, the conclusion is not believed but occupied.
आत्मनो निर्विकारस्य क्व ज्ञानं क्व च वा क्रिया । ज्ञानायत्ता बहिर्भावा अतः शून्यमिदं जगत् ॥ १३१ ॥
For the changeless Self, where is knowledge, and where is action? External existents depend upon knowledge; therefore this world is void.
निर्विकार आत्मा के लिए कहाँ ज्ञान, कहाँ क्रिया? बाह्य पदार्थ ज्ञान के अधीन हैं; अतः यह जगत् शून्य है।
