The Sun is considered to be the progenitor of Rama's dynasty, which is called the Solar Dynasty (Raghukula or Raghuvamsa – Raghu means Sun and Kula or Vamsa mean familial descendant). Rama is also known as Raghunatha, Raghupati, Raghavendra etc. That all these names begin with the prefix Raghu is also suggestive of some link with Sun-worship. The syllable 'Ra' is used in the word to describe the Sun and brilliance in many languages. In Sanskrit, Ravi and Ravindra both mean "Sun".
