विद्वाप्येकादशी तत्र पूर्वा स्याद्गृहणां तदा । यदिभिश्चोत्तरा ग्राह्या ह्यवीराभिस्तथैव च ॥ ५० ॥
vidvāpyekādaśī tatra pūrvā syādgṛhaṇāṃ tadā | yadibhiścottarā grāhyā hyavīrābhistathaiva ca || 50 ||
ទោះដឹងច្បាប់ក៏ដោយ ក្នុងស្ថានភាពនោះ សម្រាប់គ្រួសារករ (អ្នកនៅគេហដ្ឋាន) គួរយក «ឯកាទសី» មុន។ តែសម្រាប់សន្យាសី (អ្នកបួស) ត្រូវយក «ឯកាទសី» ក្រោយ; ហើយសម្រាប់ស្ត្រីមេម៉ាយក៏ដូចគ្នា។
Sanatkumara (in instruction to Narada on Ekadashi-vrata rules)
Vrata: Ekādaśī-vrata
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that Ekādaśī observance is dharma-sensitive: the correct tithi selection depends on one’s āśrama and life-condition, preserving the sanctity of the Viṣṇu-vrata while avoiding improper timing.
By regulating Ekādaśī according to eligibility (gṛhastha vs. yati vs. widow), the text frames bhakti as disciplined practice—devotion expressed through correctly performed vrata rather than mere intention.
It reflects Jyotiṣa/Vedāṅga-based tithi discernment used in vrata calendars—choosing the ‘pūrvā’ or ‘uttarā’ Ekādaśī when timing is ambiguous, based on the practitioner’s category.
