In this world every man IS ultimately an island in a way...ultimately we are all alone.....maybe not alone as in lonely but as in we are or should be self contained....Self dependent....independent....
Change is the only thing constant in this world.Nothing lasts forever yet life continues.
Thus there is a great need to be independent.To be dependent on any person,situation or thing for happiness would stunt the soul from flowing freely and would make it difficult for the world that surround also...that burden of carrying dependence .
More than the above,its a matter of responsibility....we are all responsible for our own emotions ....happiness or sadness.We shouldn't expect external environment to change us internally.
This doesn't mean we don't get attached,it doesn't mean we don't trust ,it doesn't mean we don't love or live life fully in any way...it just means that our inner strength should be what should remain the same....and what we should rely on t0 sail us through difficulties.And should relaise that to experience life ..happiness and even pain is good...its a part of life...a part of our lives and we alone are responsible for it.So no blaming in times of trouble or going overboard in happiness.
This image on the left shows what i mean by dependence...in the first picture..a leaning line ona staright line...ultmiately either the leaning one would fall or the straight one would collapse under its weightThe rest 2 can interpreted as readers want.There is no right or wrong in this case.Just as long as no separated parallel lines...then its some way towards attachment...but not dependence.
Its good to take a break from the world every now and then...and be alone...listen to your inner voice and experience the peace around you.To take pride in your hobbies .....what you do out of joy...not out of compulsion or to attain a level of perfection.Sometimes its good to be passive also.
