Grahana

When the asura named Rahu attempted to pose as a deva to receive amṛtam, the nectar of eternal life, Surya and Chandra, the deities of the Sun and the Moon, alerted Mohini, the incarnation of Vishnu.

Rahu's head was exiled to the heavens, and due to the two celestial deities' part in his decapitation, he is said to occasionally swallow them whole for a given period of time, causing the solar and the lunar eclipse.

[7] The Skanda Purana recounts a legend where sages witness a forest-dwelling woman transform into a beauty after taking a bath in a holy lake during a solar eclipse, implying that it is a means of attaining salvation.

[10] The Brahma Vaivarta Purana states that one who bathes during a full moon, an eclipse, and sacred occasions achieve the abode of Vishnu, Vaikuntha.

[13] Pregnant women are considered to be especially at risk to the effects of an eclipse, and are expected to adhere more strictly to religious bans during the phenomenon to prevent birth deformities in their children.
