Before a new chapter is begun, the old one has to be finished: tell yourself that what has passed will never come back.
Remember that there was a time when you could live without that thing or that person - nothing is irreplaceable, a habit is not a need.
Never carry things on from the past. The past is gone. Every moment be rid of it, solved or unsolved. Drop it - and don't carry parts because those parts won't allow you to solve new problems that live in this moment. Live in this moment as totally as possible, and suddenly you will come to realized, that if you live it totally, it is solved. There is no need to solve it. Life is not a problem to be solved, it's a mystery to be lived.
And if, to be sure, sometimes you need to conceal a fact with words, do it in such a way that it does not become known, or, if it does become known, that you have a ready and quick defense.
The religion of the future will be a cosmic religion. The religion which based on experience, which refuses dogmatic. If there's any religion that would cope the scientific needs it will be Buddhism.
