युगप्रजालक्षणम् ऋषिप्रवरवर्णनं च
Yuga–Prajā-Lakṣaṇa and the Enumeration of Eminent Ṛṣis
यच्चाप्यस्ति महद्वाक्यमृषीकाणां वचः स्मृतम् / अविस्पष्टपदं यच्च यच्च स्याद्बहुसंशयम्
yaccāpyasti mahadvākyamṛṣīkāṇāṃ vacaḥ smṛtam / avispaṣṭapadaṃ yacca yacca syādbahusaṃśayam
And there is also the great saying (mahāvākya) remembered of the ṛṣis—whose wording is unclear, and which gives rise to many doubts.
