Gratitude is the power to arise above your self, and accept that someone else or something else has given you what you wished for. Gratitude is a way of giving back to the world what the world gives you.
Take the case of a mother. She is a selfless person who goes on giving without expecting but a few words of kindess in return. Thank her every day for the food she cooks and for the love she shows.
Take the case of a sweeper. He keeps your driveway clean or your area fresh. If he had not done what he does everyday then you entire region is going to be filled with filth and mess. Express your gratitude to him.
This and many other cases, only go to show that gratitude is a must for all interactions. Do not hesitate to express it for this is the only way you could leave a positive impression in the world. The entire world is involved in its own regular routine. A few handful taking off time for others in itself is a big thing. So this expression of gratitude is the best way we could give back to those who do for us.
World is an empty space but what fills it is the happiness shared by those who deserve it. When gratitude is exchanged, the world is a better place as it gets rejuvenated with every gratitude offered. If there is someone who goes out of the way to do something for us, we
should never ignore this person. Express your gratitude and give them the position they deserve to be in.
When you leave the world, all that would be left are your intentions and creation.
So the next time, someone does something for you , do not forget to be thankful. Gratitude is the key to being a complete person.
