चतुर्युगाख्यान (Caturyuga-Ākhyāna) — Yuga-wise Origins and Measurements of Beings
मनुष्या वर्तमानास्तु युगं संध्याशकेष्विह / देवासुरप्रमाणं तु सप्तसप्तङ्गुलादसत्
manuṣyā vartamānāstu yugaṃ saṃdhyāśakeṣviha / devāsurapramāṇaṃ tu saptasaptaṅgulādasat
As for humans living here in the twilight portions (sandhyā) of the yugas, their measure is thus; the measure of devas and asuras has diminished by seven aṅgulas at a time.
