There is a lot of truth in most of this thread's posts.
Buddhism can be practised as a religion, as it is in some parts of South-East Asia. It can also be considered as nothing more than a philosophy of life, idea est a way to act and live. While religion worries about what happens on Earth and after(life), Buddhism can be taken as a very materialistic doctrin of how to live on Earth only. It is not a religion in the holistic sense of the term 'religion'.
However, and Cat is right, religio is the Latin word for 'connecting, bonding'. Religion is about communication with someone, something, as you like (as a confirmed atheist, I can't tell you more about that). And Buddhism do connects you to some other conscience, in fact, Buddha. Meditation is the way to reach a 'superior' mind level where you can feel some Buddha vibes (please pardon this very poor expression, I hope you see what I mean).
Habilis says: go back to science. Why not, after all. But beware, science and religion are playing in the same playground. Science has nothing to do with faith, religion has nothing to do with facts.
iMac Daddy: imagine your heart is a big sponge and that every breath you take brings back all the blood to it, cleans it and then lets it flow back to your whole body. Take long, slow, deep breathes. Try to concentrate on your blood traffic.
