Is there meaning in existence? Age-old question..the answer elusive. Without consciousness, the question would not come up. Quantum mechanics may best describe meaning: It depends on how you look at it, when you look at it and who is doing the looking.
I like to think that meaning can be experienced through certain sensations. I have two favorites: humor and love.
When you are struck with something really funny, it is like electricity rolls up in your core, then explodes. Same thing with love. I never feel more alive than when I am laughing or loving. I wish I had a really good joke to insert here because I would love to make you laugh.
