Skanda Purana — Kashi Khanda, Shloka 40
अष्टम्यां च चतुर्दश्यामुपवासी नरोत्तमः । प्रातः स्नात्वाथ पीतांभस्त्वंतर्लिंगमयो भवेत्
aṣṭamyāṃ ca caturdaśyāmupavāsī narottamaḥ | prātaḥ snātvātha pītāṃbhastvaṃtarliṃgamayo bhavet
অষ্টমী ও চতুর্দশীতে শ্রেষ্ঠ নর উপবাস করবে। প্রাতে স্নান করে সেই জল পান করলে সে অন্তরে লিঙ্গময় (শিবময়) হয়।
