How do you make your head blank?

I sat across the table from my dad and asked, “what are you thinking about, Dad?”

Dad: “Nothing,” 

Me: "I wish I could think of nothing as easily as you.”

Dad: “You just try too hard.  When you try to hard at a thing, it’s hard to sit back and enjoy it.  If you can sit back and enjoy a thing, you can think nothing of it.”

After he said that, I imagined you might find the idea insightful.

The old man has got some insights left to share before the eternal peace invites him to the eternal party.
