A thing to remember here is that these posts are strictly meant for the particular planet position. Like, today we are looking at Saturn in Scorpio, so the description given here may change for you if your Saturn is although in the sign of Scorpio but in conjunction with or aspected by other planets. --

Saturn is all that which we don't like in our life. Saturn is delay, frustration, restriction, limitation and anxiety. It is hard-work and labor. It is people of authority, like boss at your work place or father-figure at home. Saturn is Master and Servant both (depends on who uses Saturn in what way). Saturn is our Karmic debt from life. Saturn is the things we didn't treat too well in our past life. Saturn is our challenges and lessons of life. Saturn is old-age, teeth in human body, diseases, transformation etc. Saturn is discipline, organisation, structure, government, law & order etc.

Scorpio is the 8th sign of zodiac belt, hence it represents the things and energy related with 8th house of horoscope like Sudden Events, Secrecy, Dark World, Occult Science, Research, Inheritance, Serving Others, Taxes etc. Besides these things sign of Scorpio also represent transformation, means changing the whole nature upside down. Now with Scorpio, scary things start in Astrology. This is one sign which is favorite of every Astrologer, because it has maximum secrets, so every astrologer gets maximum scope of researching. This is sign about which no one can tell with precision that what will happen to the planets in it, as it is sign of secrecy itself. Scorpio is one sign where no planet is happy. Scorpio is also one of those unique signs which has 2 rulers, i.e. Mars and Ketu. Scorpio is the sign which shows our Karmic Debt in this world. Scorpio consists of next set of 2 and half nakshatras, i.e. Vishakha, Anuradha and Jyeshtha.

Saturn is Change and Transformation. Scorpio is Change and Transformation. So, this position is all about facing biggest of changes and transformations in life. There should not be any confusion about it. Whichever house it is falling in, will see the biggest of challenges or changes in life. Only favorable thing is that Saturn is a slow-moving planet. So, no change will be sudden. Saturn will give ample opportunity, indications or omens to person before bringing the final change. It is like Saturn telling them to change themselves on their own rather than waiting for an event to change them. So, person will get enough indications from Saturn that change is coming. They both also represent Death. So, when person has Saturn in Scorpio and goes through its dasha or major transit then person faces death and re-birth type of scenario when he goes through a complete change altogether in life. 

Again, impact of Saturn's effect in Scorpio will be controlled by the various nakshatra Saturn might be in. Like, if Saturn is in Vishakha nakshatra, then we need to check Jupiter's position as Jupiter is lord of Vishakha. If Saturn is in Anuradha nakshatra, then Saturn will be in its own Nakshatra. If Saturn is in Jyeshtha nakshatra, then it is impacted by Jyeshtha's lord Mercury.

Last but not the least, as I said we have to look at position and conditions both lords of Scorpio, i.e. Mars and Ketu, to finally come to know what is going on with this Saturn here. So, overall reading is much more necessary than a particular planet in sign position.
