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 Aquarius, so the description given here may change for you if your Saturn is although in the sign of Aquarius 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.

Aquarius is 11th sign of zodiac belt, hence it signifies the things and energy related with 11th house of horoscope, such as Gains, Desires, Hopes and Wishes, Large Organisations, Network Circles etc. Besides this, Aquarius also represents Scientific Thinking & Research, Uplifting the Society, Higher Goals & Rewards for all. Aquarius is made of another set of 2 and half Nakshatra, i.e. Dhanishtha, Satabhisha and Purva-Bhadrapada. Aquarius Lord is Saturn & Rahu.

This is going to be another easy one. If there is any position of Saturn which is little better to us where it sheds away its basic Tamasik nature even by 1% then it is this one. As Aquarius is Mool Trikon Sign of Saturn, this is where it becomes little better towards us, but only little. If in other signs it makes you work hard till mid-30s before it gives any result then in Aquarius, it will do so till you are 32-33. So, it is almost same, just a little bit of difference. Here Saturn makes a person work hard towards serving humanity or serving a higher cause. Here, person will either work in large organizations or he will be working hard in serving a higher cause. As Saturn represents Technology, these people are very much inclined towards new-age technology, scientific inventions and serving humanity through technology or scientific means. Overall, the best placement of Saturn where humanity is relieved by 1% :).

But the extent of this impact will always be as per the Nakshatra Saturn is in. In Dhanishtha Nakshatra, it will be impacted by Mars as nakshatra lord. In Satabhisha Nakshatra, Rahu will impact Saturn's functioning. In Purva-Bhadrapada, Jupiter will be the one impacting Saturn.

Also, as the co-lord of Aquarius, Rahu's position will have highest impact on Saturn.
