दशमविवेकः
अंशे ग्रहद्वये कुलमुख्यः ।
Take the navamsha (one-ninth part of a sign) of the atmakaraka (the planet that stands for the self). Say two planets are in it. Then the person will head his family.
एकः स्वर्क्षे कुलमुख्यः ।
Say one planet is in its own sign [in that navamsha (one-ninth part of a sign)]. Then the person will head his family.
द्वौ स्वर्क्षे स्वकुलाधिकः ।
Say two planets are in their own signs [in that navamsha (one-ninth part of a sign)]. Then the person will rise above the rest of his family.
सोत्थे गुरौ लाभे चन्द्रे कुलदीपः ।
Say Jupiter is in the 3rd house and the Moon is in the 11th house. Then the person will be the lamp of his family.
