Yes this is so true, I always immediately feel better when laughing. Even a forced laugh will almost become genuine and create the feelings of positivity 😊

It's weird, during some of my meditation sessions where I try to let go of the negativity of the days, sometimes find myself instinctively smiling and even having the tendency to just start laughing/giggling.

I guess it's like you said -

'It likewise encourages you to discharge outrage and be all the more lenient'

It allows us to release pent up energies

Laughter really is the best medicine 😆
