“The most sacred place in the world is your mind. Guard it ferociously.”
“Guard the portals of your mind.”
“For myself, I always assume that a lion is ferocious, and so I am never caught off my guard.”
“To find that which is most sacred in this world, look to that which is most violently profaned.”
“Nothing is at last sacred but the integrity of your own mind.”
“Be vigilant; guard your mind against negative thoughts.”
