Greetings, Brother / Sister!
I think Satanama is this mantra you are searching for.
This works to block any and all negativity from the outside in the same time cleansing all negativity from the inside out:
IMHO, Saturn returns are the organic part of the whole Saturnian structure of one's life, I mean natal Saturn and all his returns and all transits to important planets and stelliums we have throughout our life. this is one whole story to be analyzed in a whole.
Saturn transits to your CR/AC is a good time to analyze what is your major Saturnian / building points in life and how Saturn usually tends to realize its energies towards you. Once you realize it you can start to configure the scheme of sublimation. Knowing what your Saturn "likes" you can feed it these things in accordance to your own goals, so to say. For example Saturn adores self-criticism, asceticism, self-discipline, self-restriction, cleansing in any ad all ways (this is why the above meditation is great as well as Saturnalia practice) and a lot of building. you have to find this in the sphere your natal Saturn stands since return will trigger this sphere specifically and try to find the area relatable to this place into which you wish to invest these energies so that they keep "busy" and do not destroy all your other spheres of life you do not want them in.
Remember that the worst thing astrologer can do is restrict the house understanding with one only area of life. House has numerous ways to be realized in except the one described in the internet. Moreso, what is described as its sphere traditionally, is but a symbol of its energy. Symbol is of course taken not out of the blew and it means the energy "likes" to go there. In your case it would mean your Saturn "likes" to go into that house and sign. But it does not dictate you the version of the house realization. For example Saturn in 5th can be used for "building" in sculpture, architecture and other higher classic art demanding a lot of knowledge in building and a lot of self-discipline & asceticism, or any 5th-specific recreation sphere that demands from the author of it extreme dedication, self-discipline and asceticism. This is also great position for celibacy & childlessness and 24/7 dedication to other important things, usually classic art or lifelong platonic love (usually to the Higher Being), sometimes innovation. Saturn in 2th is said to build all types of millionaires with greatest labor and dedication because Saturn / Kronos "enjoys" crazy dedication. Saturn in 10th is a known placement for country leaders and other great leaders of extreme masses of people. Many exceptionally successful state leaders had this (presidents, Hitler). Thus Saturn shows where we tend to be the most serious and dedicated. Both Saturn and Jupiter represents Kronos / Zeus in some way and represents our dedication. The best thing to do is to ask Gods especially Zeus to lead you to healthy sublimation of this energy into something useful for the Earth instead of it needlessly destroying you for one only reason - staying lifelong unrealized.
Here are some my writings about endless spheres of 4th and 6th houses, I answered on other, non-Saturnian painful positions there but painful position is anyway stagnate energies that are unwelcome thus went "their own way", they might be described or not described by specifically Saturn, Saturn makes everything extremely serious, non-joking, demanding extreme dedication, cleanness and purity in everything:
If I have Capricorn on the cusp of my 6th house how can I strengthen it? I was asking because I have Saturn in Pisces and Neptune in Capricorn. Neptune in my 6th house combined with having Saturn in Pisces is causing major inconsistencies in my daily work routine as well as destroying my ability...

Even if the sign isn't a water sign, can planets here produce some "watery" tendencies? But more importantly, can it indicate psychic giftedness with the 4th House which rules the subconscious?

The other thing to consider is that Saturn extremely likes all kinds of building and laying foundation to everything: architecture, house / building design, blacksmiths, laying foundation to any serious affairs.
I think Saturn is so bad for most people for this one single reason - it stays unrealized for too long especially this goes for those with "I do not give a fuck" careless attitude to the world. Because Saturn is about giving a fuck about things. It is a part o care and love we so need: when Zeus and Gods start taking you seriously, your impact, start giving a fuck about your life. When we do not care about anything or anyone, we are not given fuck about either, and this is not what we would want. Trying to offset Saturn we usually forget about so many needed things we love that are ruled by Saturn.
If you have problematic position you need first and foremost think about using these energies because any problematic position in chart is about unrealized stagnate energies that went out of control. Since you did not specify where your natal Saturn is exactly I can't say anything more concrete. My idea is if you hate many "standard" realizations of this house, found in the internet search, do not panic, most of the modern internet is written by mediocrities for mediocrities, there are numerous realizations of each house including highest and most intellectual Zevist spheres. Feel free to ask Gods to guide you in specifically your case. Absolutely any and all houses can be sublimate into professions, usually in not the only sphere.
I also recommend doing God rituals to those Gods you feel most comfortable and protected with, that you feel offsetting the unwanted energy the most after which meditating on their sigil and hear their advice via inspiration.
