Rahu

Rahu is a concept from Hindu astrology rather than a physical celestial body. It refers to the ascending lunar node, the point where the Moon’s orbit crosses the ecliptic from south to north. In astrological charts, Rahu is treated as a planet-like influence (a graha) that is not a real planet but a mathematical point used to describe certain patterns of energy. Rahu is traditionally considered a malefic influence that tends to amplify whatever it touches, often associated with ambition, desire, disruption, illusion, and transformative changes. Its effects are shaped by its sign, house placement, and aspects from other planets, and by the life phase indicated by planetary periods (dashas).

Mythology surrounding Rahu comes from the tale of the churning of the Ocean (Samudra Manthan). A demon named Rahu disguised himself to drink the nectar of immortality. He was detected, but before dying he was beheaded by Vishnu. Because he had already consumed the immortal nectar, his head and body survived as two separate entities: Rahu (the head) and Ketu (the body). In this myth, Rahu and Ketu symbolize the karmic cycles and the dual forces of worldly striving and spiritual detachment that recur in astrology.

In practice, Rahu’s influence is examined in relation to a person’s birth chart, with emphasis on material goals, foreign connections, technology, and sudden changes. The strength and placement of Rahu, along with its aspects and the corresponding house, determine whether its effects are experienced as opportunities or disruptions. Rahu’s transits and periods are considered significant in predicting life events and shifts in direction, particularly in areas like career, reputation, and broader societal trends.
