Release life and you gain it (3po soul)

Soul-Junk - 3po Soul
[1956]

That's the song that's on my mind right at this very second. Specifically, the end section, where the computerized voice repeats:

Hold your life and lose it
Release life and you gain it
You grip too tight, it slips, right?
So let it go

So simple, yet so true.

Matthew 16:24-26
Then Jesus said to his disciples, "If anyone would come after me, he must deny himself and take up his cross and follow me. For whoever wants to save his life will lose it, but whoever loses his life for me will find it. What good will it be for a man if he gains the whole world, yet forfeits his soul? Or what can a man give in exchange for his soul?"

Philippians 1:21
For to me, to live is Christ and to die is gain.
