21-23. Motions of Grahas (Mangal to Sani). Eight kinds of motions are attributed to Grahas. These are Vakr (retrogression), Anuvakr (entering the previous Rasi in retrograde motion), Vikal (devoid of motion), Mand (somewhat slower motion than usual), Mandatar (slower than the previous), Sama (somewhat increasing in motion), Char (faster than Sama) and Atichar (entering next Rasi in accelerated motion). The strengths, allotted due to such 8 motions are 60, 30, 15, 30, 15, 7.5, 45 and 30.

24-25. Motional Strength for Mangal etc. Add together the mean and true longitudes of a Grah and divide the one by two. Reduce this sum from the Seeghroch (or apogee) of the Grah. The resultant product will indicate the Chesht Kendra (or Seeghr Kendra) of the Grah from 12 Rasis. The Rasi, degrees and minutes so arrived should be converted into degrees, minutes etc. and divided by 3, which will denote the motional strength of the Grah. Thus there are six sources of strength, called Sthan Bal, Dig Bal, Kaal Bal, Drik Bal, Chesht Bal and Naisargika Bal.

26-29. Bhava Balas. Thus I explained about the strengths of the Grahas. Deduct Yuvati Bhava from the Bhava, if the Bhava happens to be in Kanya, Mithun, Tula, Kumbh, or the first half of Dhanu. If Mesh, Vrishabh, Simh, or first half of Makar, or the second half of Dhanu happen to be the Bhava, deduct Bandhu Bhava from it. Should the Bhava be in Kark, or in Vrischik, deduct from it Lagn. Deduct Karm Bhava from the Bhava, happening to fall in Makar second half, or Meen. Convert the product so obtained into degrees etc. and divide by 3 to get Bhava Bal. If the balance in the process of deducting Nadir, Meridian, Lagn, or Yuvati exceeds 6 Rasis, deduct it again from 12 Rasis, before converting into degrees and dividing by 3. The product after division should be increased by one fourth, if the Bhava in question receives a benefic Drishti. If the Bhava receives a malefic Drishti, one fourth should be reduced. If Guru, or Budh give a Drishti to a Bhava, add that Grah’s Drik Bal also. And then superadd the strength, acquired by the Lord of that Bhava. This will be the net Bhava Bal.
