रवींदुयुक्ते सिंहेंगे माहेयार्किनिरीक्षिते । नेत्रहीना मिश्रखेटैर्दृष्टे बुद्धुदलोचनाः । व्ययेजो वामनयनं दक्षं सूर्यो विनाशयेत् ॥ ६३ ॥
ravīṃduyukte siṃheṃge māheyārkinirīkṣite | netrahīnā miśrakheṭairdṛṣṭe buddhudalocanāḥ | vyayejo vāmanayanaṃ dakṣaṃ sūryo vināśayet || 63 ||
When the Sun and Moon are conjoined in Leo (Siṃha) and are aspected by Mars and Saturn, and when the luminaries are afflicted by mixed planets, people become weak-minded and dull-eyed. If such a configuration occurs in the house of loss (vyaya), it destroys the left eye; if the Sun is the cause, it destroys the right eye.
Sanatkumara (in dialogue with Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhayanaka
It frames bodily suffering (like loss of sight) as a karmic outcome indicated through graha-yoga, urging the seeker to practice restraint and dharmic living while recognizing the impermanence of the body.
Indirectly: by showing that worldly conditions fluctuate under karmic and cosmic patterns, the text motivates reliance on steady devotion and inner discipline rather than on external prosperity or physical strength.
Vedāṅga Jyotiṣa: rules about conjunction (yoga) of Sun–Moon, aspects (dṛṣṭi) by Mars and Saturn, the role of the 12th house (vyaya), and specific indications for left vs. right eye affliction.
