Chapter 8 · Enemies, Wounds, Illness: the 6th House
षष्ठविवेकः
अंशात्तुर्ये चन्द्रे केतुदृष्टे नीलकुष्ठी ।
Take the navamsha (one-ninth part of a sign) of the atmakaraka (the planet that stands for the self). Say the Moon is in the 4th house from it. Ketu aspects it. Then the person may suffer from leprosy with blue patches.
Classical view, not medical advice.
लग्नेश इन्द्वारौ वा राहुकेत्वन्यतरयुतौ एकत्र श्वित्री ।
Say the lagna (rising sign) lord, or the Moon and Mars, are joined with Rahu or Ketu in one place. Then the person may have white patches on the skin.
मन्दार्कारयुतौ रक्तकृष्णाख्यकुष्ठी ।
Say Saturn, the Sun and Mars are joined. Then the person may suffer from red-black leprosy.
मन्दारचन्द्रा मेषे वा वृषे श्वित्री ।
