Mythological Story Behind Surya Grahan
According to ancient Hindu mythology, during the Samudra Manthan or Sagar Manthan, when the gods and demons were churning the ocean for Amrit, a conflict between them occurred. Disguised as Mohini, Lord Vishnu charmed the demons and commenced distributing the Amrit to the Gods. Rahu was not deceived, he sat in between the Sun and the Moon and stretched his hands to receive the Amrit. Unknowingly, Mohini (Lord Vishnu) distributed Amrit to Rahu. It was then that the Sun and the Moon acknowledged him and signalled the same to Lord Vishnu, who beheaded him with his divine discus (Sudarshan Chakra). His head flew and swallowed the Sun, causing an eclipse.

In the astrological story, after the beheading, Rahu and Ketu, the two immortal halves of Rahu, emerged out of his head and body. To reciprocate their punishment, they decided to cast a shadow on the Sun and the Moon, causing a harmful effect.
The Influence of Surya Grahan 2025
Although the partial Surya Grahan 2025 will not be visible in India, the first eclipse will coincide with the Chaitra Amavasya, which marks the beginning of the Hindu New Year and Chaitra Navratri.

The Sutak period, which usually begins 12 hours before the eclipse, will also not be applicable in India. It is believed to be an inauspicious time as the evil powers rule the zodiac signs during the Surya Grahan.
