In Vedic astrology, determining the full lifespan of an individual and the order of planetary Dasas is based on traditional insights and texts like Phaladeepika. The full lifespan is traditionally calculated as the time taken by the Moon to complete 1000 revolutions. However, in the Kaliyuga, 100 years is often accepted as the maximum lifespan according to the Vedas.
The sequence of planetary Dasas begins with the strongest among the Lagna (Ascendant), the Sun, and the Moon. Planets occupying Kendra and other important positions follow, with the strongest planet in those positions taking precedence. If multiple planets share the same position and strength, the planet with the longer lifespan period (Ayurdaya) is prioritized. If Ayurdaya is also equal, the planet that rises first after eclipse by the Sun is given precedence.
The typical order of Dasa precedence is as follows:
A planet's strength is calculated by multiplying its position by its distance from the nearest Bhava-sandhi and dividing it by the distance between Bhavamsa and one of its Sandhis.
Ayurdaya is calculated based on the strength of the Lagna (Pindayurdaya), Sun (Naisargikayurdaya), and Moon. If all three are equal, their Ayurdayas are summed and divided by three to obtain the required Ayurdaya. If only two are strong, half their sum is considered. If all three are weak, the Jeevasarman method is employed.
The Kalachakra Dasa system is utilized when the lord of the Navamsa occupied by the Moon is robust. The Nakshatra Dasa method is regarded as the most accurate.
The traditional texts provide lifespan estimates for various beings engaged in virtuous actions, such as:
These estimates depend on living virtuously, exercising control over one's senses, consuming wholesome food, showing devotion to Brahmins and Gods, and preserving family conduct.
In Vedic astrology, the sequence and strength of planetary Dasas play a critical role in the interpretation of life events and personal development. Calculating Ayurdaya and understanding the Kalachakra Dasa system provide nuanced insights into the timing of significant life milestones, reflecting the intricate balance of cosmic influences on human life.
