It is much harder to see the light when we are in defensive mode, or living in fear, worries, anxieties, because the brain is naturally as it is supposed to do, focuses on worst case scenarios to protect us.
If we throw a Light on the Darkness, the mind can now see out of the doom and gloom and see with hope, possibilities, and now the brain see’s that we have no threats anymore, so it now naturally seeks something adventurous, hopeful good loving, good healthy change and a better future.
Can you see that going from one Mode to another Mode changes the brains direction, and in each Mode the Brain/Mind obviously must do its best for you. Your fear mode is supposed to only be short lived, not a lifetime journey, so with happiness the brain quickly jumps at the chance for healthy positive change, and delights in your new faith in yourself, courage and desire to follow happiness and leave the darkness behind you forever.
