a1) we all have a clear purpose in life and must find it......... or
a2)......... we will end up achieving our purpose come what may............. to
b) ........we exist because we have sinned in our previous lives and will continue to exist till we are 'good' enough to go back to the Universal power (this being our purpose) we all came from.... to
c) .......there is no purpose in life as such; we must just learn to live every moment and take things as they come because there is very little under our control and the world is a random and dynamic place where nothing is predictable.
My mind is however inclined to believe that we all have a purpose or a mission that may be predetermined or perhaps a purpose/mission that secretly evolves with our own growth (character, ambitions dictated by the situation etc). I am not sure why every single thing that happens to us happens the way it does but I do believe in the so-called coincidences that seem to know just what we need, help us understand what is important and take us closer to what we - deep in our heart - believe we must be doing and so forth.
I think it takes a lot to NOT 'see' and 'pursue' this purpose. Though, I have no concrete ideas on what these 'bad' influences pulling us away from our actual purposes could be. (The symptoms could be lack of confidence, failure to grab and hold on to excellent opportunities etc).
Oops. I'm on the verge of forgetting what I started out to write this post for. My message - I have a strong suspicion that identifying our purpose is very easy if we just pay a little more attention. The purpose is more often than not...
a) Staring us right in our face and is as obvious as the reflection in our mirror. Almost everything we do is adding up and leading to that obvious purpose/mission.
b) Lurking just beneath the surface of our lives and all it takes may be one or more consecutive or spaced out events/incidents for it to bob up and get all our attention. Seen from another angle, all it needs is perhaps a little coincidental tap for it to emerge and show up in all its glory. In retrospect, most of the events and situations we were involved in becomes an obvious link to the newly recognized purpose.
c) Perhaps embedded slightly lower down, somewhere in the recesses of your life but it could be easily nudged out with a little bit of external help/support from the 'important' people around you (your role models, parents, teachers, friends etc. People who have the wisdom to see what's hidden within you even though it may not be visible to you)
If there are people who are convinced, during the last leg of their lives, that they seemed to have lived their lives without any clear purpose whatsoever, then maybe that was their very purpose - to simply flow along the river of life and enjoy its various currents minus a single or key destinations.
Notes: I have a couple of books that talk about identifying one's purpose in life but I'm yet to read them. Once I read them, I'll perhaps come back to this post and find out what I would 'still' agree with or disagree with. ;-)
