Discernment is about learning what is right for you, no matter what it looks like to anyone else. Ascension requires you to make your own choices, for the very simple reason that you are a unique being in the history of space and time. The path you need to navigate to unlock your own Ascension gateway is unique to you.
Discernment is purely intuitive. It is often experienced as a warm flush around the heart (if something attracts you) or a tightening in the gut (if you are being warned off). Notice when you experience these feelings, notice what choices you make, and notice the outcomes. Learning discernment is like learning to ride a bicycle. If you haven’t fallen off, you haven’t learned the limits. Don’t worry, you will.
