Okay... So why would I want to?
I'm not a meditation expert, but it helps in various ways:
It clears your mind, making you more empty (i.e more full), and more focused. You get used to being pure 'nothing', which is the fundamental substance of God. It's a way to connect on that level with your god consciousness, but it also over time gets rid of that needy, nagging part of you. The insecure, inner dialogue becomes quieter.
Things are revealed also in meditation, if you sit and are receptive you can gain answers to things you want to know. They will just come if you are clear enough.
But to me... sitting in the dark to become nothing is part of my creative rituals too.
