Ecstasy is our very nature; not to be ecstatic is simply unnecessary. 

To be ecstatic is natural, spontaneous. It needs no effort to be ecstatic; 
it needs great effort to be miserable. That's why you look so tired, 
because misery is really hard work; to maintain it is really difficult, 
because you are doing something against nature. 

You are going upstream -- that's what misery is.
And what is bliss? Going with the river -- so much so that the 
distinction between you and the river is simply lost. You are the river.
How it can be difficult? To go with the river no swimming is needed; 
you simply float with the river and the river takes you to the ocean.

The river is already going to the ocean.
Life is a river. Don't push it and you will not be miserable.
