Tithi-Nirṇaya for Vratas: Ekādaśī Rules, Saṅkrānti Punya-kāla, Eclipse Observances, and Prāyaścitta
सर्वैरेकादशी ग्राह्या दशमीपरिवर्जिता । दशमीसंयुता हंतिपुण्यं जन्मत्रयार्जितम् ॥ ४० ॥
sarvairekādaśī grāhyā daśamīparivarjitā | daśamīsaṃyutā haṃtipuṇyaṃ janmatrayārjitam || 40 ||
அனைவரும் தசமியின் தொடர்பு இல்லாத ஏகாதசியையே கடைப்பிடிக்க வேண்டும். தசமியுடன் சேர்ந்த ஏகாதசி மூன்று பிறவிகளில் சேர்த்த புண்ணியத்தையும் அழித்துவிடும்.

It stresses tithi-śuddhi (purity of the lunar day): an Ekādaśī observance must be properly timed, because an impure (Daśamī-mixed) Ekādaśī is said to negate previously earned spiritual merit.
By insisting on correct Ekādaśī practice, it frames devotion as disciplined worship—Bhakti expressed through a precise vrata that honors Viṣṇu with right time, restraint, and reverence.
It highlights Jyotiṣa/Vedāṅga time-reckoning (tithi determination), specifically avoiding “Daśamī-saṃyukta” (Daśamī-viddha) Ekādaśī when planning the vrata.
