For many things we are not ready. Until we are ready to turn off the thinking part. The brain very often stops human from being happy. So many times the doors open up offering the light and peace, but the doubts and fears doesn't let to make that step. Because experiences in the past and uncertainty about the future tells the different. Because people prefear thinking instead of feeling, they are proud HOMO SAPIENS... But only "now and here" feeling is a really happy moment. Not in the past, not in the future... Did ever sky opened the door with a hope and you wasn't ready?
