There is a thumb rule in accounting saying that every account has to be tallied and the balance of every account gets transferred to something known as Trial Balance. This will help to prepare two statements known as Profit & Loss and Balance sheet. These two statements depict the entire picture of your performance.
What if your profit and loss account shows a loss, it’ll erode your reserve from the balance sheet, and the situation will be such that you become bankrupt on the other hand if you accumulate profit you’ll have rich reserve with you.
When we enter this world we come empty-handed and the same goes when we exit. We start an account with zero balance and by the time we leave our account get tallied to the consequences of our actions in term of gain or pain.
All this is only because of one thing and that is our action. In any situation how we deal with it and what is the effect of such action will determine our Karma. In today’s world we are very fast toward our action and we don’t even know what is right or wrong, every school of thought has its own definition but what I can think of is every single destiny you decide to reach, you’ll find two-way to reach there, One would be difficult and another would be a smooth one. Since smooth one is quite easy everyone tries to go by that way when the mass of people follow in such small lane you have all differences, clashes and other man-made problem coming to your way and even in this race also few people can make it very easily reason being they are blessed with luck.
On the other hand the difficult path you’ll find very few people as nobody wants to burn their hands because to walk here you’ll require a hell lot of courage and this includes your determination, hard work, passion and many such elements which generally people hate to have. even in such cases if you can’t make it to the end you are blessed with luck in the true sense..)
Well having said all this what I feel is that soothes to pain can only be realized when you feel the pain and while walking on the difficult path will give you feeling and once you reach your destination it'll give you the fruit of your life. The theory of karma is that it’s better to hurt yourself than others as you are accountable for your action, not the others.
