In Indian Mythological texts, ‘Rahu is referred to as an astronomical body. This is one among the nine planets which are commonly referred to as Navagraha. Rahu is the planet which is believed to be responsible for all the eclipses in one’s life and thus, it is also called Shadow entity. As per the scriptures, when Amrita or nectar of immortality was released from the oceans, the Gods and demons had an altercation and fight to get it. Hence, Lord Shiva decided to interfere to protect the general interest. For this, he transformed himself into a beautiful woman named Mohini and gave the poison to all the demons.

Demons were charmed by the beauty of Mohini and thus they all drank the poison except one demon named Swarbhanu who was persistent and was not at all charmed by the beauty of Mohini as he understood everything. So Lord Shiva used his powerful chakra on him but it was not successful in killing him as he had already drunk a drop of Amrita but it did divide his body into two parts. The head was Rahu and another half (Body) was Ketu. Ketu is said to be Rahu’s sibling. Rahu is exalted in Taurus, Gemini, Cancer, Aquarius and a friendly planet in Aries.
