“When, after so many years, trying to find a purpose of my life, I did not find, questions come in my mind – whether there is at all a purpose? Are all purposes man made? Do we humans create a purpose and try to achieve, something like purposely throwing a needle in a heap of hay and trying to find the needle all our life, is having no purpose the only purpose?”
All purposes are of the human mind. It purposely creates these purposes to keep him occupied day and night. It cannot stay without a job.
