I don't know about you, but sometimes I carry alot of crap around with me. I'm not talking about the stuff in handbag, I'm talking about the junk in my emotional backpack. The stuff I carry around everywhere that weighs down my spirit. So here's a little visualization technique I made up to help lighten the load.
Go into you meditative stance. Lie down, sit.. whatever works for you. Just find a place you're comfortable that you can zone out the world.
Now imagine yourself on the bank of the a river. You're carrying a big backpack, stuffed with all the things you're worried about. Set the backpack down in the tall meadowy grass. Open it up and start pulling out your burdens one by one. Examine each weight, analyze it. Is it something you really need to worry about? If not, put it in the river and let it float away. Once you've gone through and cataloged all you troubles, only put the ones absolutely necessary to function, back into your backpack. Chuck everything else into the river and watch it float away, leaving your sight and life.
Put your backpack on a gain. Feel how much lighter it is without the extra weights from worrying about dumb things, or things you can't control.
Open your eyes and go about the rest of your day. Make sure you leave the discarded worries where they belong, away from you and your emotional backpack.
