Jai Sri Ganesha,
For man, light and heat are essential truth to live on in spirit with Atman,
The Sun that causes soul, indicate both for the Atman,
Optimize pitch of both make it easy to cultivate the virtues which yield favorable with the season,
The season is that span of the journey when the spirit departs from one entity to other, and pause for rest upon to experience the fruits of immortality,
May Lord bless all,
Thanks, please
