कन्यायामुच्चांशाद्बुधस्य परतस्त्रिकोणसंज्ञं च। विंशतिभागादूर्ध्वं क्षेत्रं त्रिविधं तु विज्ञेयम्॥५॥
In sign Kanya, the portion of 5° that is beyond the exaltation point of Mercury is called his Moolatrikona. Similarly, beyond the 20th degree therein it is his Swakshetra. Thus, the sign has a triple function: viz, Uchcha, Moolatrikona and Swakshetra.
