Vira Simhavaloka · Chapter 78
शीतपित्त — कर्मविपाकः
This Shitapitta karmavipaka chapter has a single unit. The text gives no cause and says the wrong behind it is small.
Classical view, not medical advice.
It sets one penance fast, or a substitute, with a gift of gold and feeding priests.
The English below is our translation from the Sanskrit.
Shitapitta (hives) - past deeds
अथ शीतपित्तयोः कर्मविपाके हेतावनुक्तेऽपि स्वल्पपाप त्वात्कृच्छ्रमेकं तत्प्रत्याम्नायं वा कुर्याद्धिरण्यदानं च कुर्यात् । ब्राह्मणभोजनं च कारयेत् । तेनोपशांतिर्भवति ॥
Next, in karmavipaka (fruit of past deeds), no cause is given for the two kinds of hives. Even so, the wrong behind them is small. So the sick person should do one krichchhra (penance fast), or a substitute for it. He should also give gold and have priests fed. This brings relief.
Unit 78.1 says no cause is given, and that the wrong behind it is small.
