लोकज्ञान-वर्णन (Lokajñāna-varṇana) — Description of World-Knowledge / Cosmogonic Classification
ज्योत्स्ना संध्याहनी चैव सत्त्वमात्रात्मकं त्रयम् / तमोमात्रात्मिका रात्रिः सा वै तस्मान्नियामिका
jyotsnā saṃdhyāhanī caiva sattvamātrātmakaṃ trayam / tamomātrātmikā rātriḥ sā vai tasmānniyāmikā
Moonlight, twilight, and day—these three are of the nature of sattva alone. Night is of the nature of tamas alone; therefore it serves as the restraining regulator.
