Skanda Purana — Nagara Khanda, Shloka 20
उपवासपरो भूत्वा मांसमश्नाति यो द्विजः । वृथामांसाद्वृथा तस्य तद्व्रतं जायते ध्रुवम्
upavāsaparo bhūtvā māṃsamaśnāti yo dvijaḥ | vṛthāmāṃsādvṛthā tasya tadvrataṃ jāyate dhruvam
உபவாசத்தில் நிலைத்தவன் எனக் கூறிக்கொண்டும் மாம்சம் உண்ணும் இருமுறை பிறந்தவனுக்கு, அந்த வீணான மாம்ச உண்ணுதலால் அவன் விரதமும் நிச்சயமாக வீணாகிறது।
Durvāsā
Listener: Unnamed king (implied)
