Jataka Tattva · by Mahadeva
Chapter 3 · Body, Nature, Health: the 1st House
प्रकीर्णतत्त्वम् : अङ्गविचारः (प्रथमविवेकः)
यथा तथा षष्ठाष्टान्त्यधनस्थाश्चन्द्रार्कारयमा बलिग्रहदोषजा नेत्रहीनता ।
Say the Moon, Sun, Mars and Saturn are in the 6th, 8th, 12th and 2nd houses, in any order. Then the person loses his sight. It comes from the body humour of the strongest of these planets.
Classical view, not medical advice.
