The only issue i have with this book is that it is not long enough. i have gone over it and over it many times to remind me to think of myself in a positive way. i am a huge believer is positive affirmations. i have a database of probably 100 pages of positive affirmations and many books that i use frequently. when i'm feeling down or when i want to accomplish something that i have doubts about, i pull out this book along with many others and my database and just start reading. the "light" can be any positive thing to you like God, "going into the light", or any other great feeling you have. One of my favorites said by Henry Ford is "If you think you can or you think you can't, either way, you're probably right". This book encompasses the correct way to think about yourself in the world.
