Ah the good old Greek philosophies: A healthy mind in a healthy body! Still the best rule to follow!
Would you be surprised to know that the greatest Greek philosophers also spent a lot of time in trying to determine the existence and substance of the soul and on how to elevate it? I mean Socrates, Plato and Aristotle all did remarkable works on ontology which lead to the acceptance of the existence of God... different from the gods of the pantheon.
You should include medicine in your program and follow what Hippocrates used to say “Let food be thy medicine and medicine be thy food.” (which also happens to be a Taoist and TCM precept among others).
In regard to religion, you would surprised that in its origin it was a binding factor and a driving force in nations for the betterment of Man. I mean Ronin, Strenght, Honor, Humanity, Valor, etc... are all actual moral virtue, and you guys are encouraging piety (which will be a necessity to survive in space, I haven't heard until today of a single astronaut who doesn't live by the book, pun intended, and I haven't heard of any Nasa regulation forbidding astronauts to freely express their faith, au contraire...).
The scourge of mankind has and always will be envy, greed, jealousy and more importantly ignorance.
my two cents and peace out.
