A certain deductions (called Haranas) should be applied to the calculated term of life in case if the planets are placed above the Horizon (in houses 12, 11, 10, 9, 8 or 7), inimical signs, if they are combust (too close to the Sun), or there are malefics in the Lagna. The maximum term of life given by all the planets is 120 years. This can happen only if all the planets are in their exaltation points, all the planets are under Horizon, and there are no malefics in the Lagna.
1. Chakrapatha Harana.
When the planets are placed above the Horizon, on the Western part (houses 12, 11, 10, 9, 8, and 7), they undergo the Chakrapatha Harana. The closer a planet is to the Lagna (in its Western direction), the more life term it loses. In this way, if a planet is placed in the 12th house, it loses all its life term. The reduction also depends on the nature of the planet. Malefics lose more than benefics. The Sun, Mars, Saturn and badly associated Mercury are malefics. The Moon, Jupiter, Venus and well-associated Mercury are benefics. If there are two or more planets in the houses, the reduction is applied only to the strongest planet in the house.
2. Satruksehtra Harana. When a planet is placed in the inimical sign, one-third of the term left after Chakrapatha Harana must be deducted. This reduction is not applied to Mars and to the planets that are Retrograde. In this program, this Harana is only applied to the planets(when they are not retrograde) placed in the signs of natural malefics if these malefics are not their friends.
3. Astangata Harana.
If a planet is combust (too close to the Sun), it loses half of life term that is left after Chakrapatha and Satruksehtra Haranas. Venus and Saturn are exempt from this reduction. The Moon is combust when it is less than 12º forwards or backwards of the Sun; Mars-17º Mercury-12º Jupiter-11º.
4. Krurodaya Harana.
If there are malefics in the Lagna, the Krurodaya Harana is applied to the malefic that is the closest to the Lagna. If the malefic in the Lagna is aspected by benefic, the reduction is only half from the amount calculated.
This reduction then subtracted from the total term obtained after the first three deductions.
Note. The term of life received after calculation is not something fatal. It just gives us idea about the strength of the planetary influences on our lives and health. We can compensate for the weakness of the planets by diet, proper life style and remedial measures.
