Poetry and geography
In India, we ape the west and refer to people we love as "sunshine".
Even though in reality we hate the sun. The sun is harsh in India. It causes our skin to brown more than it already is. We don't find a tan gorgeous. We find whiteness attractive - the whiter the better!! (i am talking of India as a community - not necessarily reflecting on personal preference here) The sun is not a reason for rejoicing. Sunrise - yes as it symbolizes the light after a period of darkness. But, the sun in the sky is hardly a cause of happiness and good cheer.
This explains why no regional poetry derives its inspiration from the sun - when it wants to describe a positive feeling. In fact some English songs we love to hum will not quite make the same sense in Indian languages. Let me list out a few:
1) Here comes the sun. tu ru ru ru ru - The Beatles
2) "the sun is shining everyday, clouds never get in the way for you and me" - "i love you", Martina Mcride (
