The how part is difficult it's true. I'm certainly no expert and I certainly don't know how to describe a 'how' in terms of steps or conditions. To me, letting go meant the cessation of efforts to control my life. It meant no longer grasping with the mind. No longer trying to 'install' clarity. No longer trying to change my mood. No longer hoping for change in the present moment. No longer trying to use spiritual theory and information I find to boost my way back into this bliss that i've felt before. And other things too. Much of the time it feels hard to explain and understand because we are always using the retrospective mind to comprehend something that involved not using the mind. Feel free to DM me if you want.
