Trikon

183-184. In this system the first Dasha commences from the strongest amongst the Rasis in Kon (Trikon) to Lagn (Tanu, Putr and Dharm). This system is similar to the Char Dasha. Here also the Dashas of the Rasis will be in the onwards order in the case of odd Rasis and in the reverse order in the case of even Rasis. The Dasha years will be similar to that of Char Dasha. It has been named Trikon because of the commencement of the Dasha from the Rasis in Konas.

Dirga

185-187. In this system the order of the Dashas is, as follows: the Rasi, occupying Dharm, the Rasis, receiving a Drishti from the Rasi in Dharm, the Rasi in Karm, the Rasis, receiving a Drishti from the Rasi in Karm, the Rasi in Labh and the Rasis, receiving a Drishti from the Rasi in Labh. As this system is mostly based on Drishtis, it has been named, as Dirga Dasha. Three different processes are adopted for the Movable, Fixed and Dual Rasis from Dharm, Karm and Labh. According to them, Rasi, which receives a Drishti from the Movable Rasi, is counted backwards and the Rasi, receiving a Drishti from the Fixed Rasi, is counted onwards. In the case of the Dual Rasi, if it is odd, the counting is onwards and the order is backwards in case of an even Rasi for the Rasis, receiving a Drishti.

Notes. The intention is, that from the point of view of Drishti the process of Rasi, receiving a Drishti, should be started from the Rasi, which is nearest. In this connection readers may refer to Rasi Drishtikathan Adhyaya, Ch. 8, Verse 9 and the table after that.
