Can anybody give me detailed and understandable info on these and not just a Wikipedia link?

How can I perform chakra meditation or ‘open up’ my chakras (if that’s even possible)?

I’d like to start meditating, any pointers?

I’m truly interested by these subjects, but right now I’m pretty clueless. I’d appreciate it very much if you’re knowledgable on these things and if you’d help me =)
