Chapter 4 · Going and Coming: General Rules
सामान्यगमाऽऽगमाध्यायः
यातुः पृच्छालग्नतः सप्तमस्य स्वामी यायाद्यावता वक्रभावम् ।कालेनैति प्रस्थितस्तावतेति प्राहुस्त्वेते प्रश्नतत्त्वप्रवीणाः ॥ १० ॥
Take the traveller's question chart. Find the lord of the 7th house from its rising sign. See how long that lord takes to start moving backward. The one who has left will come back in that much time. So say the experts in question charts.
Simple meaning: The traveller returns when the lord of the 7th house from the question's rising sign starts moving backward.
चन्द्रतोऽथ् यदि वा विलग्नतो द्वादशद्वितयराशिगामिनः ।
Venus, Jupiter and Mercury in the 12th and 2nd from the Moon or rising sign: no going, no coming.
बलेन सर्वोत्तमतामुपागतो ग्रहो गृहे यावति लग्नतो भवेत् ।
The strongest planet's house number from the rising sign gives the months before the traveller returns.
चरांशकस्थे किल काल एष स्थिरांशके तद्विगुणस्तु वाच्यः ।
Moving sign's navamsha: that time. Fixed: twice the time. Dual: three times the time.
