एवं सलग्नखेटानां विधायाष्टकवर्गकम् ।
त्रिकोणशोधनं कुर्यादादौ सर्वेषु राशिषु ॥ १ ॥

त्रिकोणं कथ्यते विप्र ! मेष-सिंह- धनूंष्यथ ।
वृष- कन्या - मृगास्याश्च युग्म तौलि घटास्तथा ॥ २ ॥

कर्क- वृश्चिक- मीनाश्च त्रिकोणाः स्युः परस्परम् ।

Verse 1–2

1-2 : Maharishi Parasara said - O Vipra ! After making ready the format of the Ashtakavarga of all the planets alongwith the Ascendant, in the described manner (in the foregoing Adhyaya), Trikona shodhana (Triangular Reduction) has to be carried out for all the signs. Three signs mutually located at an equidistant are known as Trikona Rashi (Triangular signs). For example, Aries, Leo and Sagittarius; Taurus, Virgo, Capricon; Gemini, Libra, Aquarius and Cancer, Scorpio, Pisces are the triads of the Trikona signs.

अधोऽधः सर्वराशीनामष्टवर्गफलं न्यसेत् ॥ ३ ॥

त्रिकोणेषु च न्न्यूनं तत्तुल्यं त्रिषु शोधयेत् ।
एकस्मिन् भवने शून्यं तत् त्रिकोणं न शोधयेत् ॥ ४ ॥

समत्वे सर्वगेहेषु सर्वं संशोधयेद् बुधः ।
पश्चात् विपश्चिता कार्यमेकाधिपतिशोधनम् ॥ ५ ॥

Verse 3–5

3-5 : The number of Rekhas obtained in the Ashtakavarga of the planets, the Sun, the Moon etc., be written below the signs of Aries, Taurus etc. Amongst the triad of Trikona signs, whichever sign has lesser number of Rekhas, the same number be deducted from the number of Rekhas of all the three signs and the remainder be written under each of them. In the Trikona signs, if any sign is devoid of any Rekha, no Shodhana would be necessary. If all the three signs are having equal number of Rekhas, the Shodhana of all the three signs should be carried out. This should be followed by the Ekadhipatya Shodhana (Reductions).
