Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 8 · Marks of Men and Women
पुरुषस्त्रीलक्षणम्
त्रित्रिकस्त्रिप्रलम्बः स्याद्वृषणे भुजयोर्नरः ।दिग्देशजातिवर्गांश्च तेजसा यशसा श्रिया ॥ १० ॥
In the full Agni Purana this is chapter 243, verse 10.
A man is 'three-long-hanging' in the testicles and arms. Next, there is one who spreads over the quarters, lands and peoples, by strength, fame and fortune... (Our text is unclear here: only testicles and arms are named for the three, and 'three-three' is not explained.)
Simple meaning: Long-hanging testicles and arms are a good mark. So is spreading strength, fame and fortune far and wide.
व्याप्नोति यस्त्रिकव्यापी त्रिवलीमान्नरस्त्वसौ ।
He who spreads far is called three-spreading. A man with three folds has three rings on the belly.
देवतानां द्विजानां च गुरूणां प्रणतस्तु यः ।
Bowing to gods, brahmins and teachers is three-bowing. Knowing the right time for duty, wealth and desire is the other.
उरो ललाटं वक्त्रं च त्रिविस्तीर्णो विलेखवान् ।
A wide chest, forehead and face are good. So are hands and feet with banner and umbrella lines.
