WE OFTEN speak of nine planets and we have the mantras and stotras for the nine planets. In Sanskrit the word graha means a planet which has a gravitational pull (Graha), the power to attract. The constellations of our zodiac are called Nakshatras. The others are called stars (tara). What are the nine planets ? The Sun is a star, not a planet. As the “Aditya Hridaya” taught by Agastya to Sri Rama observes: Nakshatra graha taranam adhipah.
