Well, if you have basic understanding of English you will. ‘I let go of the dog leash so my dog could run free’

‘I quit holding onto my dog as he was pulling so much and that cat had it coming’

No meditation required

To be a bit less mystical than my original comment…

I used to think “letting go” meant “giving up”…

“Letting go” in the Alan Watts sense means being willing to give up on the means — not the outcome. I’ll let go of the way I’ve been doing things, let a small part of me die, so I have a better chance of meeting the outcome I am looking for. The psychological establishment might call that flexibly minded or low aversion to loss.

Giving up is convincing yourself a difficult the outcome/goal wasn’t worth it — instead of finding new means to reach it.

The scripture says….
