Skanda Purana — Brahma Khanda, Shloka 46
तदर्धं रोगिणां चापि सुस्थे न्यूनं न कार येत् । अपि सर्वनदीतोयैर्मृत्कूटैश्चाप्यगोपमैः
tadardhaṃ rogiṇāṃ cāpi susthe nyūnaṃ na kāra yet | api sarvanadītoyairmṛtkūṭaiścāpyagopamaiḥ
สำหรับผู้ป่วย แม้ทำเพียงครึ่งของนั้นก็พอได้; แต่ผู้มีสุขภาพดีไม่พึงทำให้น้อยกว่ากำหนด แม้น้ำจากแม่น้ำใดๆ และก้อนดิน—แม้มิได้เตรียมไว้เป็นพิเศษ—ก็พึงใช้ประกอบการชำระให้บริบูรณ์

FAQs

The sick may do reduced śauca; the healthy should not reduce it; purification may be done using any river water and ordinary clods of earth.
