The happiness feedback from making others happier -- even if just less miserable -- is the most excellent feeling known to man. Once a person tastes it, nothing else will ever compare.

Lovingly serving others' happiness is a part of the asymmetric dynamics of the human universe, only accessible and operant in the world of free will and the ability to learn and manifest right from wrong, love from callous disregard or even cruelty, creation or destruction.

Peace be with you, though I hardly need say that to someone who already understands peace beyond what most can comprehend. Thanks for having your boots on the ground.
