World Weary and Faith - 信仰

Merriam-Webster defines world weary as : feeling or showing fatigue from or boredom with the life of the world and especially material pleasures. German author Jean Paul coined the term : Weltschmerz ( meaning world-pain or world weariness ) to denote the kind of feeling experienced by someone who understands that physical reality can never satisfy the demands of the mind. 
Ajahn Chah in his “Clarity of Insight” mentioned : The sense of world-weariness that grows with insight, however, leads to detachment, turning away and aloofness that comes naturally from investigating and seeing the truth of the way things are.It is free from attachment to a sense of self that attempts to control and force things to go according to its desires. Rather, you let go with an acceptance of the way things are.....  The three fetters of personality view, doubt and blind attachment to rules and practices that are normally present underlying the way you view the world can't delude you or cause you to make any serious mistakes in practice. This is the very beginning of the path, the first clear insight into ultimate truth, and paves the way for further insight.

It is alright to feel world weary with a conscious mind as the understanding of how this world is evolving is truly wearily. 

Have faith in your believe to seek the understanding, and accepting the world as it is .
