षोडशयोगाध्यायः
अथ शीघ्रग्रहस्य मन्दग्रहस्यैकांशातिक्रमणे ईसराफयोगः ॥ एकांशापूर्त्तौ कलानामतिक्रमणेपीत्थशालयोग इति जीर्णटीकाकृत् ॥
Next, when the fast planet passes the slow planet by one degree, the israpha (planets moving apart after an aspect) combination forms. While the one degree is not complete, it is still ithasala (planets moving toward an exact aspect), even if minutes have passed.
Simple meaning: Israpha forms one degree after the meeting. Before the full degree, it is still ithasala.
अत्रेसराफयोगस्सौम्यग्रहजनितश्शुभ इत्युक्तं हिल्लाजे ॥
Israpha made by a good planet is good: the work is not spoiled.
अथ शीघ्रग्रहो मन्दमतिक्रम्य द्वादशांशाभ्यधिको भवेत्तदापि मूसरिफः शुभफलद एवेत्युक्तं यादवेन ॥
Israpha past twelve degrees: it is good. Between one and twelve degrees past, musaripha is not good.
अत्रोदाहरणमाह स एव ॥
Example of israpha: Jupiter at 16 and Mercury at 17 means no marriage yet. Mercury at 28 brings it.
