The head region joined with body of snake and become Raghu Bhagavan. The body portion joined with snake’s head become Kethu bhagavan. Ragu and Kethu bhagavan doesn’t forgive the suryan and chandran. Chandran is started consuming by Ragu. This leads chanran to rely on the Lord Shiva for blessings. Lord Shiva has blessed the chandran to get back the power of growing back after 15 days. So, we can see the waxing and waning of the Chandra (Moon) in the sky. The Lord also blessed the Moon and adorning him in his head. Anyone prays the Moon has belief of regain the power and enjoyment in life.
King Dakshan gave all the 27 daughters to chandran in marriage. Among the 27, Chandra’s favourite consort is Rohini. This leads the Chandra to spend more time with the rohini. Other ones made a complaint to their father. King Dakshan got angry and cursed Chandra that the beauty and awesomeness slowly disappears by every day. Chandra is to be relied on Lord Shiva to escape from the curse. Lord Shiva blesses him to regain the awesomeness day by day. This led waxing and waning of Moon. Shiva also adorns the Chandra in his forehead.
