The Account of Mohinī (Mohinī-kathanam): Ekādaśī Nirṇaya, Daśamī Boundary, and Aruṇodaya
एतेन देवकार्यं च सिद्धं भवति शोभने । सूर्येन्दुचारा तिथ्यास्तु दशम्याः प्रांतगामिनी ॥ १० ॥
etena devakāryaṃ ca siddhaṃ bhavati śobhane | sūryenducārā tithyāstu daśamyāḥ prāṃtagāminī || 10 ||
ഇതിനാൽ, ഹേ ശുഭേ, ദേവകാര്യവും സിദ്ധമാകുന്നു. സൂര്യ-ചന്ദ്രഗതിയനുസരിച്ച് നിർണ്ണയിക്കുന്ന തിഥികളിൽ, അവസാനം സമീപിക്കുന്ന (പ്രാന്തഗാമിനി) ദശമി തിഥിയേ സ്വീകരിക്കണം।
Narada (in dialogue within the Uttara-Bhaga’s Tirtha/Vrata instructions; traditionally framed as Narada teaching, often to Sanatkumara or in a Suta-narrated setting)
Vrata: Daśamī-based rite (connected contextually to prior Yama observance; name not specified)
Primary Rasa: shanta
Secondary Rasa: adbhuta
It teaches that ritual efficacy (devakārya-siddhi) depends not only on devotion but also on correct sacred timing—specifically, choosing the proper tithi boundary so the act aligns with cosmic order (ṛta).
Bhakti here is expressed as disciplined worship: devotion becomes “siddha” when performed with reverence and with the right vrata-timing, showing that loving worship is strengthened by careful observance.
It highlights Jyotiṣa (Vedāṅga astrology): tithi is defined through the Sun–Moon relationship, and the verse specifies prānta (end-time) selection—an applied rule of ritual calendrics (tithi-nirṇaya).
