Matthew 4:17 Heavenly!

"Repent, for the kingdom of heaven is at hand."

To put it briefly, the moment you pick up an attachment, 

the functioning of this lovely apparatus called the human heart is destroyed.

You must choose between your attachment and happiness. 

You cannot have both.

(Your attachment) came from a lie that your society and your culture 
have told you, or a lie that you have told yourself, namely, that without this 
or the other, without this person, or the other, you can't be happy.

Do you want your attachment, or your freedom and happiness?

If you wish to be fully alive you must develop a sense of perspective.

If you live long enough, a day will easily come when it 
(this trifle you got so upset about) 
will cease to matter. 

It will not even be remembered--your own experience will confirm this. 

Just as today you barely remember, 
and are no longer the least bit affected by, 

those tremendous trifles that so disturbed you in the past.

The unavoidable conclusion is that no thing or person outside of you 
has the power to make you happy or unhappy.  

It is you and only you who decides to be happy or unhappy, 
whether you will cling to your attachment or not in any given situation.

Repentance, 

the refashioning of the heart, 
has begun and the kingdom of God--the gratefully carefree life of children--
has come within your grasp at last 
and you are about to reach out and take possession of it.
