Brahmopadeśa on Saṃnyāsa, Tapas, and Jñāna (ब्रह्मोपदेशः—संन्यासतपोज्ञानविमर्शः)
इस वृक्षपर रहनेवाले (मन-बुद्धिरूप) दो पक्षी हैं, जो नित्य क्रियाशील होनेपर भी अचेतन हैं। इन दोनोंसे श्रेष्ठ अन्य (आत्मा) है, वह ज्ञानसम्पन्न कहा जाता है ।। अचेतन: सत्त्वसंख्याविमुक्त: सत्त्वात् परं चेतयतेडन्तरात्मा । स क्षेत्रवित् सर्वसंख्यातबुद्धि- गुणातिगो मुच्यते सर्वपापै:,संख्यासे रहित जो सत्त्व अर्थात् मूलप्रकृति है, वह अचेतन है। उससे भिन्न जो जीवात्मा है, उसे अन्तर्यामी परमात्मा ज्ञानसम्पन्न करता है। वही क्षेत्रको जाननेवाला जब सम्पूर्ण तत्त्वोंको जान लेता है, तब गुणातीत होकर सब पापोंसे छूट जाता है

Vāyu said: “Upon this tree dwell two birds—figures for mind and intellect—ever active, yet themselves insentient. Superior to these two is another, the Self, which is called endowed with true knowledge. Prakṛti, the primordial ‘sattva’ beyond enumeration, is insentient; distinct from it, the individual self is awakened and illumined by the inner Ruler, the Supreme Self. When that knower of the field comes to comprehend all the principles of existence, he transcends the guṇas and is released from every sin.”
वायुदेव उवाच
Mind and intellect are active instruments but not self-luminous consciousness. True awakening comes from the indwelling Supreme Self (antarātmā/Paramātman). When the knower of the field discerns the principles of prakṛti and the Self, he transcends the guṇas and becomes free from moral and karmic impurity.
Vāyudeva delivers a doctrinal instruction using the metaphor of a tree with two birds. He identifies the ‘birds’ with inner faculties (mind and intellect) and points beyond them to the Self and the inner Ruler, framing liberation as the result of discriminative knowledge and guṇa-transcendence.
