Rahu (राहु)

Rahu is the ascending lunar node personified as a graha in Jyotisha and Hindu mythology, with traditions that emphasise eclipses, ambition, obscuration, unconventional paths and worldly desire in astrological interpretation. Images of Rahu are commonly recognised through serpentine or severed-head form and eclipse imagery. The name is also encountered as North Lunar Node. Some details change across sectarian, regional and temple traditions, which is important when writing an accurate overview. A useful treatment should separate mythology, theology and living practice: first outline the deity’s identity and principal narratives, then explain iconography and devotional significance, and finally note contemporary worship, festivals, temples and household customs where they are genuinely relevant.
