"Food is nourishment, shelter is home, and clothing is protection. But mental food is food from the tree of life - wisdom, science, history, food for your mind. Mental clothing is how you carry yourself - the way you walk, the way you move and speak. If you have clothed yourself in righteousness, even the bummiest clothing has dignity. And mental shelter is the mind’s protection from the evil atmosphere - the lies and corruption of the outside world. So if you have these three jewels, your home is like a king’s even if you’re living in a shack."
