Multiply the daily motion of the planet by the Sun's Equation of the Center and divide by 21,600; applying this result makes the motion true to the solar day.
Modern Technical Commentary:
Defines the 'Bhujantara' or Equation of Time. It corrects for the fact that terrestrial days are measured by the Sun's return to the meridian, which is slightly variable because the Sun's own motion is non-uniform.

Defines the Sighrocca (Point of Conjunction).
- For Outer Planets (Mars, Jupiter, Saturn): The Sighrocca is the Mean Sun.
- For Inner Planets (Mercury, Venus): The Sighrocca is the planet's
own mean motion.
Calculate the Sighra Kendra (Anomaly of Conjunction).
