Ch. 67. Trikon Shodhana in the AshtakaVarg

1-2. The sage said. O Brahmin! After preparing the AshtakaVarg of all the Grahas, including Lagn, Trikon Shodhana has to be done for each Rashi. A Trikon is made of three Rashis equidistant from each other. Thus Mesh, Simh and Dhanu, Vrishabh, Kanya and Makar, Mithun, Tul and Kumbh, Kark, Vrischik and Meen form the Trikonas of the Rashis.

3-5. The Trikon Shodhana (rectification) should be done by writing the Rekhas in the AshtakaVargas of Sūrya etc. under the Rashis Mesh etc. Amongst the Trikon Rashis the Rashi, which has lesser number of Rekhas, should be allotted Rekhas, arrived at by deducting its number of Rekhas from the greater number of Rekhas of the three Trikon Rashis. No Trikon Shodhana is necessary, if any of the Trikon Rashis has no Rekha. Shodhana should be done, if all the three of them have equal number of Rekhas, that is a zero should be written against all of them. Thereafter Ekadhipatya Shodhana should be done in the same manner, described later. (For Shodhana of the AshtakaVarg of a Grah the first thing to be done is to see, in which Rashi the Grah is posited. Beginning from that Rashi, the names of the 12 Rashis should be written and then the names of the Grahas, posited in them, should be mentioned against them. Thereafter the Rekhas, gained by that Rashi, should be written below them and the number, achieved after Shodhana, below it)
