Tithi-Nirṇaya for Vratas: Ekādaśī Rules, Saṅkrānti Punya-kāla, Eclipse Observances, and Prāyaścitta
पूर्वा गृहस्थैः कार्यात्र यतिभिश्चोत्तरा तिथिः । उपोष्यैव द्वितीयेति केचिदाहुश्च भक्तितः ॥ ५२ ॥
pūrvā gṛhasthaiḥ kāryātra yatibhiścottarā tithiḥ | upoṣyaiva dvitīyeti kecidāhuśca bhaktitaḥ || 52 ||
ଏଠାରେ ଗୃହସ୍ଥମାନେ ପୂର୍ବ ତିଥି ପାଳନ କରିବେ, ଯତିମାନେ ଉତ୍ତର ତିଥି। କେତେକ ଭକ୍ତ ଭକ୍ତିଭାବରେ କହନ୍ତି—ଦ୍ୱିତୀୟ ଦିନେଇ ଉପବାସ କରି ବ୍ରତ କରିବା ଉଚିତ।
Sanatkumara (in instruction to Narada, within the vrata/tithi discussion)
Vrata: Ekadashi (contextual)
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that devotional observances must be aligned with dharma and eligibility: householders and renunciants may follow different tithi rules, yet the core aim remains sincere devotion expressed through disciplined fasting and observance.
Bhakti is shown as both rule-guided and heartfelt: while tithi selection follows tradition (earlier for gṛhasthas, later for yatis), some devotees emphasize devotion by fasting on the following day as well, prioritizing earnest worship and restraint.
It reflects Vedāṅga Jyotiṣa-style tithi-nirṇaya (lunar-day determination) used in vrata scheduling—how to choose the correct observance day when tithis shift, with different prescriptions based on āśrama (life-stage).
