Surya Grahan, solar eclipse, is widely mentioned in the Holy Scriptures of Hinduism. There is also an interesting myth regarding the occurrence of Surya Grahan. It happened during the Samdura Manthan (churning of ocean) episode in the Puranas. Rahu (Demon) and Mohini, an incarnation of Lord Vishnu, are the main characters in the incident.
The Amrit (elixir) that was obtained from churning the ocean was cunningly stolen by Ausras (Demons). Lord Vishnu took the form of Mohini, a beautiful damsel, to win back the Amrit. She achieved her mission by enamoring the Asuras, they fell for her beauty and handed over the Amrit to her.

Mohini returned to the Devas and started distributing it. Devas sat in a line and mohini gave a portion to each one of them. Rahu, an Asura, who found out that they were tricked took the form a Deva and sat in the line between Chandra (Moon God) and Surya (Sun God).
When Mohini approached Rahu, Chandra and Surya realized that Rahu was not one among them and soon identified him as an Asura. Mohini soon severed the head of Rahu which flew into the sky. Rahu’s, depicted in the form of a Snake head occasionally, continued to live and decided to avenge Surya and Chandra.
Thus periodically Rahu engages in a war with Surya and Chandra. The Chandra Grahan (Lunar eclipse) and Surya Grahan (Solar eclipse) takes place when Rahu gobbles up Moon and Sun respectively. Surya and Chandra then fights to free themselves.
The most important precaution to be taken during Solar Eclipse is not to watch the eclipse with naked eye. Watching the Eclipse with naked eye might cause permanent damage to the eye or blindness. The safest method of viewing a Total Solar Eclipse is by projection, in which a small opening is used to cast the image of the Sun on a screen beyond the opening.

Fasting during Grahan

The Use of Metal or Sharp Objects
There is a popular belief that pregnant women should not use sharp metal objects like knife, pins etc during the Grahan period. In simple terms they should not cut anything during the period or should not wear pins etc. Some people suggest that it will be hard to stop the blood flow if there is a cut on the body during the period. But this has no proper scientific backing.
