ईषत्स्पर्शे च दौः स्वास्थ्ये राजराष्ट्रभयेऽपि च । अत्यागतिकाले च मंत्रस्नानं समाचरेत् २४ ।
It is enough if one performs mantra snāna when one is slightly indisposed, or when there is danger from the king or when there is civil commotion, or when there is no other way or when one is about to undertake a journey.
