Transit of planets and vedhas . Influence of each planet varies from its period, sub-period and sub-sub-period (Mahadasha, Anterdasha and Pratyanterdasha) during transit. As a result native experiences auspicious and inauspicious results according to the planetary position.Vedhas of SunWhen Sun is in the 3rd, 6th, 10th or 11th house from the Moon-sign, it gives auspicious results but when any planet gets placed in the 9th house and Sun placed in 3rd house it causes Vedha to Sun and Sun does not give auspicious results. Sun in the 6th house has Vedha due to the planet which is placed in the 12th house. Similarly, planet in the 4th house causes Vedha to Sun when placed in the 10th house and Sun in the 11th house has Vedha because if a planet is placed in the 5th house. Saturn does not causes Vedha to Sun and give auspicious results in the transit.Vedhas of MoonMoon is an auspicious planet and give beneficial results when placed in ascendant, 3rd, 6th, 7th, 10th or the 11th house. If any other planet except Mercury is placed in the 9th, 3rd, 12th, 4th or 8th house from Moon-sign, there is a Vedha to Moon. Mercury does not cause Vedha to Moon.Vedhas of MarsAlthough Mars is known as a malefic planet it give auspicious results when placed in 3rd, 6th or the 11th house, in the birth-chart. Any planet placed in the 12th, 9th or 5th house causes Vedha to Mars when placed in 3rd, 6th or 11th house respectively. Mars’s Vedha reduces auspiciousness of Mars.Vedhas of MercuryPlacement of planet Mercury in the 2nd, 4th, 6th, 8th, 10th and 11th is very auspicious and native becomes a a wise and intelligent person, due to this auspicious position of Mercury in birth-chart. Planets placed in 1st, 3rd, 5th, 8th, 9th or 12th house in birth-chart causes Vedha to Mercury. Moon is a friend of Mercury that’s why it does not cause Vedha to Mercury and the native gets auspicious results during its transit.Vedhas of JupiterJupiter is a benefic planet and it give auspicious results when placed in the 2nd, 5th, 7th, 9th or 11th house.

Vimshottari and life span When we talk of past life's, does it not beg the question, how about this life? How long will it last? What is the ceiling or max life expectency? This is Ayush or age determining considerations. Pending ones lot-in-life e.g. individual, [ manusya-ayus ] celestial [deva-ayus], animal [triyag ayus] or a hell being [ naraka ayus] various life spans are possible.

For the individual, on this planet in this yuga ( this time period), ones life say the wise, is vimshottari or 120 years. This knowledge is from Parasara muni (the Jyotisha of the first degee). Ya gotta ask why not an even 100, or the familur 108 (which I subscribe to, based upon another dasa period system)? Let's take a look:

Saturn as Yama , His Hand In ThisThis one-hundred-and-twenty is coupled to Saturn, Sani, also known as Yama. It is Yama that meters out the length of life. So if connected to Sani, we see that one trip around the sun = 29.5 years. For one's life to be 'complete' it is to cover the 4 Periods or ayana's of life: Dharma (that which upholds individual life or one's duties), Artha ( wealth creation), Kama ( fulfilling one's desires) and then Moksha ( enlightenment or establishing one SELF).If we multiply 29.5 years X 4 periods we get 118 years. I will assume Sri Parashara's knowledge is much more advanced then mine and rounded to 120 years because he knows more, trying to keep it simple, etc. I can assure you this 120 is not an approxiation, or best efforts! Some also think the following:The vimshottari dasha cycle of 120 years = 43,830 days, whereas, using the 360 days years, this amounts to 43,200 days. Now why would one use 360 days vs. a 365 day year? One year = one trip around the sun or completing a total 360 degree circle…so each day is worth 1 degree. Hence a 360 degree year is logical and then can work on any planet (brilliant I may add).

Now, note this 43,200 days. It resembles the number of years in Kali Yuga that is, 432,000 years, and it is not uncommon to write this as 43,2000 even though I find it confusing! Hence the length of Vimshottari dasa life span is a subset of the Kali Yuga duration… as Parasara shows consistency of his wisdom and dictums.

Side note, I used this word dasa , which is period or duration. Vimshottari dasa is a 120 year period. Other dasa periods are also available , there are 32 different types of dasa periods one can access and calculate, pending ones chart. My chart sugests that I should access Astottari dasa for a total of 108 years possible ayus.

Based Upon The Yuga In PlaceThe notion then is the yuga determines ones life span.That is , Dwapar, Teta and Krita Yuga's are 2X, 3X and 4X times as long as kali duration, all based on this 432,000 years, and 43,200 days. So, one's life span can be potentially 2X to 4X the life span potential of Vimshottari ayus or from 120 years to (4X120) 480 years of potential life. This 480 when added together is 12 [4+8+0]. This 12 is one complete revolution around the zodiac ( 12 signs or rasi's) where one experiences the fullness ( Bhuma) of life in Krita Yuga ( called sat or truth yuga) where most if not all of the population is enlightened beings. Fullness on the indiviual, famly, social and world levels. Fullness of Dharma, Artha, Kama and Moksha.
