Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
उद्धिज्जानि च तान्याहुर्भूतानि द्विजसत्तमा: । द्विजवरो! जो पृथ्वीको फोड़कर समयपर उत्पन्न होते हैं, उन प्राणियोंको उद्धिज्ज कहते हैं
udbhijjāni ca tāny āhur bhūtāni dvijasattamāḥ |
风神伐由说道:“噢,二生者中之最胜!诸圣贤宣说:凡诸有情,于其时至,破土而出者,名为‘芽生’(udbhijja)。”
वायुदेव उवाच
The verse teaches a traditional dharmic-cosmological classification of life: some beings are ‘udbhijja’, defined as those that emerge by splitting the earth at the appropriate season—highlighting an ordered, time-bound natural law (ṛta) recognized by sages.
Vāyu-deva is instructing a twice-born interlocutor in a didactic passage, explaining the category ‘udbhijja’ among types of living beings, using the sages’ authoritative definition.
