What we desire and what we get, there is always an imbalance.We desire a lot of things in our life but it is not always possible to get everything we desire. Even if we achieve what we desire, then we aspire for more. Human desires ends with the end of this life only.
So, if we achieve this clarity within us then, the pangs of success and failure, achieving and losing, profit and loss, all will subside and there will not be any sadness among people.
The question is, how to achieve this clarity.
