In Persian, The term BHA means light, especially used for the Suns Light, The flame of sun or something that shines like the SUN or fire, as they say “Bar e Aftab”, means “Bright light of the Sun”.

So, word BHARAT may means ‘one who is engaging in the flame of sun or Maybe it means someone who has devoted for that light, Also Bharat can means "devoted to light " or a place that is devoted to be engaged in the light.

The name Bhārat, is also a descendent of Bhāratā. The Rigveda mentions of the kingdom named - Bhaāratas. Which is believed to have come from an ancient king named Bharat. They are related to the historical ancient civilization of Indus River.

We don’t have the other part in Persian, But there is a similar sound word as “raha” which means “always stay free forever” (one that do not belonged to anything), maybe they are related, I don’t know about this second part.
