It's the same as you do, when orientating yourself on a map, out in nature. This is the very practical reason why it is so important to accept what is. It is your location on the map. Everything else follows from here. 

And that accepting takes as long as it takes. That acceptance goes together with letting go (as mentioned above) and it needs to enter the level of your cells (your inner truth).

You can't fool yourself by telling: „everything is ok“. Nothing will change then. You may ask, what can I do, if resistance is stronger than acceptance?

Stay in the present moment, at least for now and watch your thoughts and emotions. Try it for just now. There is some time later, to "practice" resistance again, if you must.
