It may look very strange when I say this, but it is difficult to take a jump from misery; it is easier to take a jump from happiness. It is easier to take a jump when you are happy because with happiness courage comes, with happiness the possibility of a higher bliss opens, with happiness the whole world looks like a home. You cannot be adventurous when you are unhappy. Adventure needs a subtle happiness in you.
Then you can leave the known. You are so happy that you are not afraid of the unknown. And the happiness has become such a deep phenomenon to you that you know that wherever you will be you will be happy. With the positive mind you know there is no hell, and wherever you are the heaven will be. You can move into the unknown because now you know that heaven moves with you.
