Mean Node (Rahu/Ketu)

The Mean Node represents a mathematical averaging of the Moon's nodal position, smoothing out the small oscillations caused by the Moon's elliptical orbit and solar perturbations. Unlike the True Node, which tracks the instantaneous wobbling position, the Mean Node moves steadily backward through the zodiac at roughly 19 degrees per year. Classical Vedic astrology (Jyotish) traditionally uses the Mean Node because it preserves the mythic narrative of Rahu (ascending) and Ketu (descending) as smoothly progressing karmic forces. The difference between True and Mean Node positions is typically less than two degrees but can be meaningful for precise dasha timing.

Your Rahu (North Node) and Ketu (South Node) in the Vedic chart represent karmic currents and soul lessons. Using the Mean Node, TriAstra honors how classical Vedic astrology has always described these points—as steady rulers of your karmic axis rather than wobbling daily indicators.
