For this ritual, it is best to go deep into a wooded area, if you can access one. If not, any nature will do. Once you are there, either yell/scream out anything that is making you feel anger, rage, resentment, hurt, frustration, pain etc. If you feel you can’t literally scream, you can do it in your own mind, write it out, smash something (safely), or find another way to express your anger.

To add to this ritual, you can make a fire (again, if safe to do so in your area) and write out/draw representations of the things you need to let go of. Then you can place them in the fire and watch them burn. Generally this ritual is more active than a meditation or simply sitting in nature. The idea is to engage your body and senses and to feel part of the natural environment.
Here’s a poem I created after a hitbodedut practice that you can read/respond to as part of the ritual if desired.
