Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
एकायनगतौ स्यातां सूर्याचन्द्रमसौ यदा । तयुते मंडले क्रांत्यौ तुल्यत्वे वै धृताभिधः ॥ १७४ ॥
ekāyanagatau syātāṃ sūryācandramasau yadā | tayute maṃḍale krāṃtyau tulyatve vai dhṛtābhidhaḥ || 174 ||
Apabila Matahari dan Bulan bergerak pada ayana (laluan) yang sama, dan dalam maṇḍala itu bujur (krānti) mereka menjadi setara, maka yoga/masa itu sesungguhnya dinamakan Dhṛta.
Sanatkumara (in dialogue with Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta

Vedāṅga Jyotiṣa: determining a named yoga/time-condition via the Sun and Moon’s relative motion and the equality of their celestial longitudes (krānti) in the maṇḍala.
