I'm wondering if anyone here has suggestion for book or tapes. Just from checking amazon.co.uk, i've come across products by Jon Kabat-Zinn. Are they any good?

As someone whose particular problem was with racing and intrusive thoughts, I'm finding that meditation does really help to calm the mind, stabilize thinking and clear-out the rubbish. The many visualization videos on youtube were particularly helpful. By the way, are visualization and mindfulness the same or different things?
