Meditation transformed my stress levels.
It's hard to learn to do, but is guaranteed to produce results, and is one of the psychological interventions with the most effective evidential profile. Go onto PubMed, and look for free at all the healthcare settings it has been tested in. The evidence is overwhelming.
Change that - it is easy to learn to do; it is hard to commit to doing it, and not just give up, declaring yourself 'special', 'unable' or beyond help.
I now teach it.
Some thoughts about accessing meditation pathways, and their different advantages and disadvantages:
1. Secular pathways - MIND workshops, local groups, university counselling services, mindfulness meetings etc. Advantages: free of religious baggage. Disadvantages: often mindfulness in the abstract is all they offer - they don't offer a plan of what to do with your mind once you've found it. They're often time limited (ie, fixed-length courses). They're not that inspirational (you're likely to be meeting in a backroom at the local library or community centre, not a nice building with a cafe and a restaurant and nice art and lots of light).
2. Buddhist pathways
2a. Tibetan-inspired pathways. Advantages: they offer basic mindfulness meditations, but also meditations on really practical things, like being at work, being angry, arguing with folk, being jealous. Lots of support and practical guidance. They're cheap. They're ongoing. Disadvantages: come with quite a lot of ritual and some of your basic common-or-garden religious BS (who's in, who's out, what happens after you die, etc.).
2b. South-Asian (Thai, Vietnamese etc.) and Japanese (Za-Zen) inspired pathways. Advantages: very little religious baggage (no stand up, sit down, say this, do that, etc.). Disadvantages: quite intellectual and theoretical; often not that applicable in everyday life. Rely on self motivation a lot - you're left thinking problems through, rather than getting practical advice. In this style, you focus most of all on breathing and calming the mind - very good, but not much good when you're having an Aspie moment and need a strategy for dealing with it, I found.
Having tried them all, I went for 2b because it's cheap, practical, and ongoing - and I just ignore all the ritual stuff. They're happy with me ignoring it - they let me teach some of their classes. That's how relaxed they are!
