From Sūrya Siddhānta — The Sun's Treatise of the Heavens, taught by Acharya T Krishnatrey. This lesson is free to read.
<pre data-block="statement">What this chapter covers | The remaining chapters map the sky. Chapter 7 classifies the close encounters of the star-planets — the "wars" (yuddha) and meetings (samāgama) — and heliacal setting in the Sun's glare. Chapter 8 fixes the fixed stars, giving each nakṣatra a polar longitude (dhruvaka) so the moving planets can be located against a steady background. Chapter 11 defines the pātas, the precisely computable moments when the Sun and Moon share equal declination — Vaidhṛti and Vyatīpāta.</pre>
