Greetings, Brother / Sister!
I am not answering your question on a square, sorry. I only comment your statement on the beautiful astrological statement.
I wish to remind you first and foremost that according the available rectification in the internet, Saturn in 6th house belongs to some most healthy people such as BKS Iyenger. And this is not one person with great health, long life and painless death that I saw with Saturn in 6th. Saturn can be greatest force especially for Zevist who does yoga and tai chi / 24/7. Having anything powerful (Saturn, Mars, Pluto or any higher planets) in 6th is great because 6th is about work and self discipline, study, career, everything we so love and which is so great about us: all our normal spiritual and physically spiritual practices: yoga routine, breathing technics, all chaolin kung fu, tai chi, qi gong, falun gong and endless practices of Chinese Taoist Alchemy, TCM etc. All so sweet things we usually love, all kind of inner style work in martial arts, all kind of spiritual work with body. Maybe becoming TCM healer, reiki and acupuncturist yourself especially with Martial planets such as Mars. Greatest achievements might be made with gravitative 6th, by gravitation I mean stelliums, power planets, higher planets, critical degrees etc. (all being Rx first and foremost) what people usually consider "problems" and what is in reality talents and powers, Saturn being the first in this list, especially Rx one.
As for Saturn in Pisces the best thing written on this was by HP Hooded Cobra 666 (great posts recommended to collect):

And TG Blitzkreig:
I have seen some comments about doing a Saturn square, and it seems that this would be alright. Pisces, after all, has it's own meaning and energy. I was thinking that a Saturn square specifically for harnessing the meditative and spiritualism of Pisces would be a good idea as this would make...

So with all this: Atlantis age Ancient experience + extreme yogic talent you have wonderful opportunity to resurrect some very Ancient Pagan knowledge throughout your life like BKS Iyengar did in regards to our spiritual practice. Or you might be as creative in modern medical science in this regard.
Saturn in higher octave always gives extremely high pure energies to the house it stands in. In 5th it would not let people go whoring around, in 6th it would not let people lead unhealthy self destructive lifestyle, in 10th - it would not let their life stay useless or unimportant, etc. If people insist on doing it wrong Saturn is known to punish them, and the lower octave comes.
Desire you good luck with great chart!
