युगप्रजालक्षणम् ऋषिप्रवरवर्णनं च
Yuga–Prajā-Lakṣaṇa and the Enumeration of Eminent Ṛṣis
लक्षणं ब्राह्मणस्यैनद्विहितं सर्वशाखिनाम / हेतुर्हन्तेः स्मृतो धातोर्यन्निहन्त्युदितं परैः
lakṣaṇaṃ brāhmaṇasyainadvihitaṃ sarvaśākhināma / heturhanteḥ smṛto dhātoryannihantyuditaṃ paraiḥ
This is the mark of the Brahmana, enjoined in all branches of tradition. From the root ‘han’ the term ‘hetu’ is remembered; others declare it as ‘nihanti’—that which destroys.
