षोडशयोगाध्यायः
अथ परिपूर्णमुथशीललक्षणमुक्तं योगसुधानिधौ ॥विकलिकाकलिकादलहीनकश्चरखगोल्पजवादथवा समः ॥मुथशिलं सकलं सफलं तदा फलति तद्यवनो मुनिराड् जगौ ॥
Next, the definition of complete ithasala (planets moving toward an exact aspect) is given in the Yogasudhanidhi. The fast planet may be short of the slow one by seconds, minutes or a part. Or it may be equal. Then the ithasala is complete. It is then fruitful and gives its full result. So the Yavana, the best of sages, said.
Simple meaning: Complete ithasala: the fast planet is a little behind the slow one, or equal. It gives full results.
भविष्यन्मुथशीलयोगलक्षणमुक्तं वामनेन ॥
Future ithasala: the fast planet at a sign's end is about to reach the slow planet in the next sign.
समरसिंहमते वर्तमानमुथशीलयोगोयं भविष्यन्मुथशिललक्षणमुक्तं तेनैव ॥
Future ithasala by Samarasimha: the fast planet is behind the slow one with fewer degrees than the orb.
अत्रेत्थशालयोगे पृष्ठस्थे शीघ्रे वक्रिणिसतीत्थशालफलाभावः अग्रस्थे मंदे वक्रिणि सतीत्थशालफलविशेष इतिसंप्रदाययुक्तिः ॥
A retrograde fast planet behind removes the result. A retrograde slow planet ahead makes it special.
