DASHA-05)Codified in Brihat Parashara Hora Shastra Chapters 50 & 73 and Jaimini Upadesha Sutras Adhyaya 2, Narayana & Sudarshana Chakra Dashas operates under the mathematical invariant Narayana (1–12y per Rashi) ; Sudarshana (1 Year = 1 Sign / 1 Month = 1 Sign): Narayana Dasha progresses through the twelve sidereal signs (Padakrama) starting from the stronger of the first or seventh house, with each sign's duration (1 to 12 years) measured by counting from the sign to its planetary ruler, while Sudarshana Chakra rotates three concentric wheels anchored to the Lagna, Moon, and Sun at the uniform rate of one sign per year of age.
SHASTRIC MECHANICSMathematical Formulation & Structural Rules of Narayana & Sudarshana Chakra Dashas
In Brihat Parashara Hora Shastra Chapter 73, Maharishi Parashara reveals the Sudarshana Chakra ('Discus of Vishnu') to evaluate every single year of life from three simultaneous reference frames: the inner ring places the birth Lagna at the top (physical events), the middle ring places the natal Moon at the top (mental and relational events), and the outer ring places the natal Sun at the top (career and vitality). In any given year N, the sign corresponding to ((N minus 1) mod 12) + 1 from each of the three references governs that year, subdivided into twelve 30-day months and twelve 2.5-day Pratyantaras.

Exaltation adds +1 year; Debilitation subtracts -1 year |
Lord in own sign grants full 12 years; dual lords (Scorpio/Aquarius) use the stronger ruler in classical Jyotish horoscopy. |
