The way

Bien provides us with practices and background understanding about how to cultivate, practice, develop, and actually live the Buddhist saying “There is no way to happiness; happiness is the way”—positive Buddhism emphasizing the good news that joy and the inherent freedom of being are our birthright and potential, rather than entirely dealing with suffering and its causes, the not self, and other such challenging facts of life from Buddha’s ancient perspective, traditionally posed in negativistic terms to exhort and motivate the old-world faithful.

The underline part is pretty tough to understand “There is no way to happiness; happiness is the way.” I presume this may mean something like happiness is already available so we don’t need to look for it. Do I understand it right?

And one more thing, live the Buddhist saying means live up to the Buddhist saying?

Thanks in advance!
