Chapter 8 · Marks of Men and Women
पुरुषस्त्रीलक्षणम्
तारकाभ्यां विना नेत्रे शुक्लदन्ती द्विशुक्लकः ।गम्भीरस्त्रिश्रवो नाभिः सत्त्वं चैकं त्रिकं स्मृतम् ॥ ८ ॥
In the full Agni Purana this is chapter 243, verse 8.
'Two-white' means the eyes, apart from the pupils, and the teeth are white. 'Three-deep' means the voice, the navel and sattva (the pure, calm quality). These are held as one set of three. (Our text is unclear here: the print has 'trishravo', read as the voice.)
Simple meaning: Two-white means white eyes and teeth. Three-deep means a deep voice, deep navel and deep inner calm.
अनसूया दया क्षान्तिर्मङ्गलाचारयुक्तता ।
These are the signs of sattva: no envy, kindness, patience, good conduct, purity, generosity and bravery.
त्रित्रिकस्त्रिप्रलम्बः स्याद्वृषणे भुजयोर्नरः ।
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.
