Dissatsfaction with mundane realities in life?

 "The mundane realities that define most people's lives" - A phrase I took notice of in a novel that I read and included in my list of literary quotes.
I had a dream yesterday wherein I cried in exasperation to a friend, "But we need to find some purpose in our lives  (or was it the word meaning that I used)"

In Buddhism amongst many durkha (or sufferings) in people is the feeling of insubstantiality in life, a form of existential crisis if you will usually accompanied by feelings of hollowness or emptiness.

In my last blog I discussed the 3 personality types in Buddhism.  It does not take much to know that I belong to the aversive type ie. the type that finds things inadequate, an everlasting sense that something is lacking but not knowing what. So I may spend a lot of time analyzing myself whilst letting each moment pass and losing it.

A lot of this unsatisfactoriness stamps from the perception of "I" which then leads to endless questions pertaining to what is it for "Me" in this world, in this life, "My Life" that is. Albert Einstein calls this "I" preoccupation an optical delusion, as per his quote below:

“A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security” 

So even this so call search for meaning or substantiality in the egoistic "I" can be a delusion. Focusing on each moment and letting go of the "I" preoccupation provides an avenue for liberation and inner security as per Einstein's quote above.

Yes "mundane realities that define most people's lives" should be fine when unencumbered, isn't it?
