तत्र वेद्यमयताप्रकाशो दिनं वेद्यस्य विचारयितरि लयो रात्रिः ते च प्रकाशविश्रान्ती चिराचिरवैचित्र्यात् अनन्तभेदे तत्साम्ये तु विषुवत्

tatra vedyamayatāprakāśo dinaṃ vedyasya vicārayitari layo rātriḥ te ca prakāśaviśrāntī cirāciravaicitryāt anantabhede tatsāmye tu viṣuvat

And these two — luminous manifestation and repose — owing to the diversity of long and short durations, exist in endless variation; but when the two are equal, there is the equinox.
