Maharṣi Parāśara names the chapter “Spaṣṭa Bala Adhyāya” where the emphasis is on spaṣṭa which means clearly perceived or discerned i.e. distinctly visible, is plain and intelligible. Unlike the vimśopāka bala which depends on the strength of the planet in the environment (varga), this gives a clear picture of its independent strengths. Spaṣṭa-bala is based on the longitude which is another meaning of the word spaṣṭa. This is the real strength of the planets. Before we jump into calculations and strength estimations, here are a few lessons that would give us a better understanding of the concepts used by Parāśara.
