The Sage said — O Brahmin! Now I will tell you about the effects produced every year and every month by the twelve houses in their dasas and antardasas according to the Sudarśana Chakra. Under this system every one of the twelve houses beginning from the 1st is allotted a dasa period of one year. Thus every year in 12 years a house becomes the Ascendant of the year and the remaining become 2nd the house of wealth, 3rd the house of brother and so on. (This means in the 1st year the 1st house will be the Ascendant and in the 2nd year the 2nd house will assume this role. Ultimately in the 12th year the role of the Ascendant is taken over by the 12th house.) Every year every house will have an antardasa of one month. By following the method of the Ascendant of the year, here also there will be an Ascendant of the month. The first antardasa will be of the first house and then will follow for 12 months the antardasas of the other houses, every house assuming the role of Ascendant by turn. Every house gets pratyantar dasa of 2½ days and vidasa of 12½ ghatikas. The same method is to be adopted for assessing the effects of houses in pratyantar dasas and vidasas.

एकभे द्वौ त्रयो वा चेत्‌ तदा लग्नात्‌ फलं वदेत्‌ । ।21।। यदि लग्न, सूर्य व चन्द्रमा में दो या तीनों तत्त्व लग्नभाव में ही हों तो लग्न से फल कहना चाहिए । वास्तव में जन्मलग्न तीन हैं — उदयलग्न, चन्द्रलग्न व सूर्यलग्न । इन तीनों पर समवेत विचार करना ही सुदर्शन चक्र विचार है ।
