I'm new to workings, but is there anything I can do to safely provide some kind of relief or endurance?
I think you can focus on Solar energies, sending to this person Sun energies, like the Rune Sowilo for example simply visualized and vibrated into this person's Aura. Algiz also is a good Rune, you can shield the person from negative energies coming, by daily use of Algiz.
The point is, the "internal emotional engine" of the person will be very dark with a Saturn return, in many cases, so the person would be unable to see the positive side of life and loose hope easily in front of any hardship coming. Simply talking, about positive things or qualities of this person, will lift his/her internal emotional side, and self-esteem and sense of hope, causing his/her 3rd chakra to react and generate more positive energies. This is not a working but, supporting in words and good intentions a person in hard days, may be of great help. This might be a little draining for you, as you will employ personal energies, so not being excessive in this is important. But the other person mat reward you with gratitude, sending back positive energies to you, creating a loop. A perfect example of how an SS person may be changing for the good, reality around him.
In short, you may be the Satanic engine for both transforming your and his/her energies into more positive vibrations, by interacting with the target person. Provided, the person is not too xian or delves too deeply into enemy programs, as this may vanish many of your efforts.
