"Oh right, just let go, but HOW exactly do I go about doing that?" Letting go is hard because it implies we are releasing something but getting absolutely nothing in return. That seems inherently a bad deal, so we resist creating this uncomfortable void. We avoid it. We avoid the void. We unintentionally hang on too tight to what is past, refusing to release our grip, even if what we are actually clutching on to is past misery.
Holding on too tight means we are letting go in a hard way. The people who move on the fastest and get the shiny new thing quickest - they are the ones who let it go easy. The thing is this: when you let it go hard, then it seems hard to let the new thing into your experience. When you let it go easy, you open the way up for it to come in easy.
Obviously I don't have a scientific quantifiable study for this, you are just going to have to take my word for it then try it out. Let's face it; if the old way isn't working you might as well try the new!
Look around, and you will see this subtle principle in action left right and centre.
We have a saying: "easy come, easy go". It's the ultimate happy-go-lucky mantra. What's even more powerfuI , I believe, is to deliberately apply this in reverse: Easy go, easy come. Let it go easy. Let it come easy. Stop looking back and wrestling with it. If you want the new thing, file away the old thing with ease. When you let it go easy, you let the next thing come easy.
