Nadi astrology claims to be an ancient system attributed to the rishi (sage) Bhrigu, who is also venerated as author of the Brihat Parashara Hora Shastra (though traditionally Parashara is the author). The legend: Bhrigu made predictions about human lives, and these predictions were recorded on palm leaves, preserved in temples and archives in South India.
Modern reality: Most "nadi texts" in circulation today are 200-500 years old, not ancient. Some may contain pre-classical ideas; others are transparent inventions or corruptions. The Kerala Nadi, Tamil Nadi, and other regional texts diverge significantly. No unified, canonical Bhrigu Nadi text exists.
What Nadi claims to do: Predict specific life events (marriage date, children, health crises, business gains, death approximation) with precision. Unlike Parashara (which gives general life themes) or KP (which requires a horary question), Nadi purports to read a chart and declare "You will marry on this date, have two children, face a health crisis at age 45."
Core principle: Fixed planetary degrees (not houses, not signs alone) are the primary tool. A planet at 15°23' is read differently than the same planet at 15°45', because the degree carries specific meaning.
Scope of this track: Teach the Nadi method as it is practiced today by contemporary astrologers (especially in India), not as some imagined ancient authority. This means: examining the degree system, direction analysis, combination reading, and then critically assessing the system's actual evidential standing.
Warning: This track will be honest about Nadi's strengths (specific event predictions, psychological insight) and its weaknesses (lack of falsifiability, post-hoc reasoning, low accuracy rates in rigorous testing). Nadi works best when used as a hypothesis-generating tool, not as absolute truth.
