"Protect his very soul" is derived from the quote "protect your very soul" -- No matter what kind of person you are, no matter how hard you work or what you do, do it protecting the most important aspect of yourself--your soul, your heart, your spirit--and you can survive in a mess of a world. The most important thing in the world is to be yourself and stick to what you believe in. With that kind of disposition in life, you can live happily and tackle just about anything. I used 'his' soul instead of 'your' soul because the former phrasing dedicates the usertitle to him rather than to myself or to the reader. I want to protect him that protects me, and that knows me in my purest sense. As for who he may be, he knows who he is. He's my best friend.
