Chapter 90 · Shiroroga: past deeds
शिरोरोग — कर्मविपाकः
अपरं च ब्रह्मचारी पूर्वजन्मनिप्रायोपवेशनेन नैष्ठिकादिव्रतत्यागी शिरोरोगी भवति । पंचाशद्ब्राह्मणभोजयेत् । उद्यन्नद्येत्यृचं जपेत् । कुष्मांडीभिर्जुहुयात् ।
Also: a brahmachari (celibate student of the Veda) may have given up his vows in a past life. These are vows such as the lifelong vow of a student. He gave them up by fasting unto death. He may suffer head trouble. He should feed fifty brahmanas (priests). He should do japa (repeating a mantra) of the rik (Vedic verse) that begins "udyann adya". He should do homa (fire offering) with the Kushmandi verses (a set of Vedic verses).
Classical view, not medical advice.
अपरं च ब्रह्मचारी पूर्वजन्मनि भिन्नकांस्यपात्रे भुक्त्वा एकदेशशिरोरोगी भवति । तदा अक्षिभ्यामिति सूक्तमष्टोत्तरशतं जपेत् । चरुघृताभ्यां जुहुयात् । वैद्यशास्त्रोक्तान्यौषधानि दद्यात् ।
Also: a brahmachari (celibate student of the Veda) may have eaten from a broken bronze vessel in a past life. He may suffer head trouble on one…
ब्रह्मचारी यदाश्नीयाद्भिन्नपात्रे विशेषतः ।
A brahmachari (celibate student of the Veda) may eat from a broken vessel. Then, most of all, he may have head trouble on one side. So says Narada.
इति नारदीयपुराणवचनात् । द्वादशब्राह्मणान्भोजयेत् । इत्यर्द्धशीर्षरोगः ।
This comes from the words of the Naradiya Purana. He should feed twelve brahmanas (priests). This ends [the part on] pain in half of the head.
