Meditation really helps with the Chaos stuff (reference our other recent thread)
I learned to meditate well from a Paranormal Psychology class. The professor was awesome and super qualified. However, the meditation description lasted about 30 minutes of one class.
The basic idea is to get quiet, relax by concentrating on letting go of each part of your body, maintain breath control - which includes deep breathing done slowly. Then let your mind go. Literally, every meditation system does that. The guided meditations here on Spells8 do it (and that voice on the meditations is awesome). The SO can lower her heart rate by up to 20 points or more in one 10 minute session. She doesn’t build mind palaces but she does fall asleep sometimes. 
Another way is a variation of it all and that is self-hypnosis which does all those steps and there are lots of guides on that, too.
