Brahmopadeśa on Saṃnyāsa, Tapas, and Jñāna (ब्रह्मोपदेशः—संन्यासतपोज्ञानविमर्शः)
आजीव्य: सर्वभूतानां ब्रह्म॒वृक्ष: सनातन: । एनं छित्त्वा च भित्त्वा च तत्त्वज्ञानासिना बुध:
ājīvyaḥ sarvabhūtānāṁ brahmavṛkṣaḥ sanātanaḥ | enaṁ chittvā ca bhittvā ca tattvajñānāsinā budhaḥ ||
Vāyu said: “This ancient ‘Brahman-tree’ is the very livelihood and support of all beings. The wise person, however, cuts it down and splits it apart with the sword of true knowledge—discerning reality as it is and severing the roots of delusion.”
