षोडशयोगाध्यायः
भविष्यन्मुथशीलयोगलक्षणमुक्तं वामनेन ॥राश्यंतगः शीघ्रगतिः स्थिरस्य भागान्विवक्षुः परराशिगस्य ॥यदा भवेत्तं प्रवदंति योगमेष्यं भविष्यत्फलदं सदैव ॥
The definition of future ithasala (planets moving toward an exact aspect) is told by Vamana. The fast planet may be at the end of a sign. It is about to reach the degrees of the slow planet in the next sign. They call this the coming yoga. It always gives results in the future.
Simple meaning: 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.
वर्तमानमुथशिलोदाहरणमाह यादवः ॥
Present ithasala example: Mars in Scorpio at 16 degrees, Sun in Leo. The gain of a kingdom depends on the degrees.
