Annual Horoscope 2016 for all signs: www.AstroMNC.com
Shani is usually well-placed in the horoscope if your past life(s) karma with respect to masses is good. If you have donated money, land to masses and overall helped masses in overall aspects like building hospitals, schools (for poors), Anna-chhatra (Fed poor people): You have good karma with masses and better position of Shani in the Horoscope. The subtle yet omnipotent & omnipresent Law of Karma would make the masses pay you back in this life/birth in equal and opposite manner -- As simple as that.
Energy can neither be created nor be destroyed -- Every force has equal and opposite force but they act in opposite directions. All these are nothing but spiritually – which represents the "law of karma" in scientific manner.
The same way the folks mentioned above must have done a LOT in their past life(s) to do betterment of masses. The masses paid them back in their Shani mahadasha.
Some Shani formations in the birth-time horoscope Shani could show acute issues in Shani Mahadasha or Antardasha:
(1) Shani close to Mangal or opposite to Mangal or both drushti on each other. As much close degrees as many acute issues with increasing intensity.
(2) Shani close to Moon or Sun or closely aspecting them with 1 3 7 or 10 Drushti. More close the degrees -- more and certain results.
(3) Shani aspecting ANY planets of the horoscope with 1 3 7 or 10 Drushti. More close the degrees -- more and certain results.if planets in 6 8 12 then more severe the issues and results after a lot of hardwork and once the deficit is paid off.
(4) Shani in some Kaarmic constellations such as Moola, Ashlesha & also in some specific degrees such as the first degree of the FIRE signs and the last degree of the water signs (Last degree of Meen -- not much of an issue though as it is DevGani nakshatra - Raj Thackeray -- Rather it shows all around ability.)
The way to reduce Shani mahadasha issues are NOT any Puja or Yadnya or Mantra or even the Gemstones!!! There are two ways to pay off the Shani Mahadasha's past Karma:
If Shani in 10th house, do seva of your father no matter how your relation is with him.
If Shani-Mangal close to each other: Help your siblings in life as they need it.
The earlier you start with this the lesser the issues in Shani mahadasha.
Of course, regardless of good or bad: Shani Mahadasha requires discipline of all the actions, conservative approach in spending, in eating etc. EGO should be avoided at any cost as folks who do not have much money are spending money for you!! Just imagine if they find out you are being egotist when they are spending time and energy for you.
If Shani mahadasha and Sadesati at the same time affects your temperament and moral too much then HANUMAAN Sadhana is THE ONLY upaay for getting enough courage to face the effects of this. Finally it is YOUR OWN creation of this life (Sadesati) or past life/lives (Mahadasha). :)
Basic: Mahadasha/Antardasha should be predominantly analysed for past life karma (good or bad). They are about results of the past karma in this life. Instant Karma or "Kriyaman karma" is about actions of this life being paid off in this life and not carried forward -- here current movement of planets helps analysis of that (i.e. when we say 5th Guru, 8th Shani and so on -- they are usually analysed from the Moon Sign). However, all Gochar planets and their relations with the horoscope planets also show the "TIMING" of the fruits of the Mahadasha and Antardasha. So what and how is from Mahadasha and Antradasha and WHEN is to be determined by the Gochar planets.)
