The position of Sukr at the time of retrogression and immediately before and after retrogression is not possible to be exactly known. The Jyotishi should correctly work out the same through various systems and ascertain the placement of Sukr in the heavens.

To know the Navamsh position of a Grah, multiply its longitude by (?) and divide by 12 and the Navamsh position is revealed.

The longitude of a Grah should be multiplied by 12. Add to the product the longitude of the Grah and divide by 12. The process will reveal the Rasi, Amsh sphutas of the Grah.

To Candrs position, add one eleventh of Suryas longitude and one fourth for other Grahas. If Sukr and Budh are combust, or are rising after heliacal setting, or are retrograde, then addition of subtraction should be made by doubling Suryas longitude and not otherwise.

The Sun-God should be worshipped by offering red flowers, Akshata and Sandal with folded hands and then the Grahas should be worshipped. The querist after doing so shall honour the Jyotishi according to his capacity.
