That was just describing the emotion, but yes, I advocate it.

Pros: It feels several kinds of good. It improves mood afterwards, both directly (serenity, happiness) and indirectly (feeling loved improves self-esteem, feeling loving improves patience). It improves courage, motivation, and focus. It's a short-term fix for anxiety (which works even on partial success). It increases aesthetic appreciation. It's interesting, though most of the fun bits (like hallucinations) aren't universal.

Cons: If you attribute it to an external source, it can give you wrong beliefs. If you practice it in a group, it'll bind the group more than you might want. You might acquire some weird compulsions (I can't write "G-d", I occasionally have to stare at things). Some of the props might be expensive, depending on what works for you.
