It's quite possible that all you need to do to wake up is to get completely straight/correct about what is true and what is false. If you're upset, it's because you believe in something false and think it's the truth, which means you believe that some aspect of the truth is not true. You just need to be straightened out and clarified on what's really true here. This is the only process needed.
Once you are completely clear about what the truth is and what is false, it will be totally obvious that the ego is 100% false and unbelievable. But when you're not clear about what the truth is, you will experience upset and be offended by the very falsety that you believe is attacking you. And it's only attacking you because you believe in it.
Kind silly, and highly contradictory, how we WANT what we DON'T WANT.
