Brahmopadeśa on Saṃnyāsa, Tapas, and Jñāna (ब्रह्मोपदेशः—संन्यासतपोज्ञानविमर्शः)
अव्यक्तयोनिप्रभवो बुद्धिस्कन्धमयो महान् | महाहंकारविटप इन्द्रियाडुकुरकोटर:
avyaktayoniprabhavo buddhiskandhamayo mahān | mahāhaṃkāraviṭapa indriyāḍukurakoṭaraḥ
风神伐由说道:“此伟大的(宇宙)之树,出自未显之源;其干由觉知之智(buddhi)所成。其巨枝为我执(ahaṃkāra)之‘我’感;而其中的孔穴与空腔,即诸根——感官之器。”
वायुदेव उवाच
The verse maps inner psychology and cosmology onto a ‘tree’ structure: the unmanifest is the root-source, intellect is the stabilizing trunk, ego-sense is a major branching principle, and the sense-faculties are the hollows through which experience flows. Ethically, it points toward discerning these components, loosening identification with ego and senses, and cultivating discriminative wisdom (buddhi) as a basis for restraint and liberation-oriented conduct.
Vāyu-deva is explaining a doctrinal model of embodied existence using a metaphorical tree. He identifies successive principles—unmanifest source, intellect, ego-sense, and the sense-organs—so the listener can understand how experience and bondage arise through the mind-sense complex.
