The Spiritual trait is a trait that makes the activities associated with the wellness skill more enjoyable for your sim. Teen+ sims can have the trait, and it affects game-play mainly in the area of buffs (see function). It is a standalone trait, that you'll see along with the regular EA traits in Create-A-Sim. I designed it to allow sims to mimic the sort of new-age spirituality that has become pretty popular in the last few decades. The Spiritual trait is an emotional trait for sims.
