Skanda Purana — Mahesvara Khanda, Shloka 52
भास्करार्घं विना पातः कृतं सर्वं च निष्फलम् । तस्याहं श्रोतुमिच्छामि विधिं विधिविदां वर
bhāskarārghaṃ vinā pātaḥ kṛtaṃ sarvaṃ ca niṣphalam | tasyāhaṃ śrotumicchāmi vidhiṃ vidhividāṃ vara
若不向婆斯迦罗（太阳神）奉献阿尔伽（arghya），则一切诵持与修行所作皆成无果。故我愿聆听其正当仪轨，噢，通晓法仪者中之最胜者。

Listener: Nārada
Scene: A devotee performing various rites—japa, homa, scripture recitation—yet the scene shows a missing arghya to the rising Sun; the Sun’s presence dominates the sky, indicating that the rite remains incomplete until arghya is offered; then the devotee turns east with a water-vessel to complete it.
FAQs
Daily worship is perfected by honoring Sūrya; neglecting arghya undermines the intended merit (puṇya) of one’s practice.
No single tīrtha is named in this verse; the focus is on the universal nitya-karma of offering arghya to Sūrya.
The necessity of Bhāskara-arghya is stated, and the listener requests the detailed vidhi (procedure).
