Sanatana Dharma Philosophy
According to Puranas, the birth of Rahu and Ketu dates back to earliest of times.‘Samudra Manthan’ is regarded as one of the most important events in the history of Hindu civilization. Following which, Solar and Lunar eclipse are also associated with ‘Samudra Manthan’. When the ocean was churned by the Asuras and Devas, ‘Amrit’ was produced. This Amrit was stolen by Asuras and to obtain the Amrit, Lord Vishnu took incarnation in the form of a beautiful damsel ‘Mohini’ and tried to please and distract the demons. On receiving the Amrit, Mohini came to Devas to distribute it to them.
‘Svarbhanu’, one of the asuras changed his appearance to a deva to obtain some portion of the Amrit. However, Surya (Sun) and the Chandra (Moon) realized that Svarbhanu was an Asura and not one of the devas. Knowing this, Lord Vishnu severed Svarbhanu’s head with his discus, the Sudarshan Charka.
However, even though his head and body became separated, they still remained immortal as the separate entity because before his head was served, he managed to drink a drop of the nectar from the Amrit. The Head is known as Rahu and the headless body is the Ketu. Since then Rahu and Ketu constantly chase the Sun and the Moon for revenge as they are the cause of separating the head and body of the Asura Rahu. It is a popular belief that when they succeed catching Sun and Moon they swallow them causing Solar or Lunar eclipse but they can’t hold them for long and Sun and Moon emerge again intact as they also had nectar and are immortal.
