How do you relax your mind?

I love to write or watch music videos. I could also look at art for ages.

I don't know if the mind can be "tamed," but to relax it, meditation works well. And it can involve just sitting with your closed eyes for 15 or 20 minutes, reciting a mantra or not - or, by watching a river or stream or sitting by a lake, watching the birds fly by, sitting in front of a nice fire in the fireplace.... lots of ways. And if you find it hard to let go of worries, you can visualize taking them out of your head and putting them in a jar, then putting the jar on a shelf and leaving it there for the time you're in meditation, knowing after your meditation, you can put the thoughts and worries back inside of your head. But let it be okay that they're not inside of you, just for the time being.
Just drop all resistance and think of nothing. When thoughts arise (and they will), picture each thought, regardless of what it is, turning into a cloud above your head and blowing away behind you. Good Luck.

Sometimes I retreat in my mind to fantasy, kind of like reading a book where you get lost in something else and forget about your stresses.

That’s easier said then done I think. Good answers below. My method is to work or take action. If a conflict, I try to face it as soon as possible. If it’s today and feeling just overwhelmed with responsibility I take a 10 minute break and get back to it. If it’s bigger than that I just tend to internalize it and put on my “under control “ mask. Not recommending that.

How do you relax your mind?

Exercise (especially long walks, they’re meditative) or writing/expressing myself in some way :)

Get things done that are within my abilities; take one thing at a time.

I try to he outside as much as possible

Music and there is this breathing exercise that I do midday when I am stressed that I also teach to my biz clients and employees, it is very powerful

Music and writing... I stopped writing for very long time. I was writing a lot before. It's hard to get inspiration now.

Think of solutions, what ever causing it. Work on it like a challenge and enjoy fixing it.
If can't, just give up and move on

Draw. Read. Watch some movie that’s going to make me bawl so I’m distracted by the runny nose and puffy eyes and general misery.

Meditation.. try too feeling your breathing.. comes in and out..

meditation.....tame and train....tame and train

Run eat chocolate

Music and isolation

With music.

Think about God and his words or sometimes think about my imagination

Music, drinks, sexy times, computer games, and stand-up comedy. Oh, and poetry.
