षोडशयोगाध्यायः
यदि नीचो नीचेन च मुथशिलकारी यथा रिपुर्द्विषता ॥तद्वत्तत्कंबूलश्चन्द्रोपि विनाशकोमुष्मिन्निति ॥
If a planet in nicha (low point) makes ithasala (planets moving toward an exact aspect) with another low planet, it is like a foe with a foe. So too its kambula (the Moon supporting the link of two planets). In this, even the Moon is a destroyer.
Simple meaning: Two low-point planets in ithasala spoil the matter, even with the Moon's support.
अत्र मुथशिलकारिणोर्ग्रहयोरेकं नीचं न सम्भवति त्रयाणां लग्नेशकार्य्येशचन्द्राणान्तु सुतरान्न सम्भवति तस्मादेकगृहगयोरेव मुथशीलयोग इति व्याप्तिर्गतैव ॥
Two planets in one sign can never both be in their low sign. So the claim that ithasala needs one sign falls.
उक्तश्चतेजस्सिंहेन ॥
Ithasala and kambula can form between planets in different signs.
अन्येपुनराहुः ॥ राशिचक्रे शीघ्रग्रहस्याग्रे यदा मन्दग्रहो भवति तदेत्थशालयोगो नेतरथा ॥
Another view: ithasala only when the slow planet is ahead of the fast one.
