Delight, Joy
If you can guard your soul from bad things you'll always feel delight and joy. It's hard to guard your soul from everything though, so take all the joy you can, while you can.
Imagine guarding yourself from all the bad things in the world. No more politics, religion, internet trolls debating the two, it's all guarded from your precious soul. Ahhh, it's so joyous to be unburdened.

The delight you feel is so great that it becomes permanently etched (えつ) in your soul and even your face.
Picture joy etched on your own face. No one can get you down.
