Well again a question and an answer, but yes this one is a valid one too. This intended to tickle the guts of all us as we always never ever get to understand "What is important in Life?"
Well to start the post I would say that we all want certain things in life, viz. a decent job, money, house, food, friends, family, etc. (Plz. don't go by the ordering of the words here they are just written as they came to my mind ;-)) and so a human goes about achieving this right from his/her commencement of life/when he starts realising that he is a human.
Down the line we do forget what we want inside. What I am trying to get to is something that is an inner desire of a person (Believe me it is difficult to put in words too... I am trying my best here...). I am not talking about the saintly things of life but an innate demand from our soul, if you'd like to call it like that, or probably something that would make us feel that yes we have done our bit and achieved something.
Without beating around the bush, I would like to say that the most important thing in life is "Inner Happiness".
Now what is Inner in happiness?? Well that's a good question. The answer lies inside you. This happiness is something that makes you feel comfortable, secure, peaceful and happy. Don;t we all crave for this little thing so much that we think that maybe by earning more money we might get it, or by travelling, by becoming the King of the world, by ruling the unruly, by becoming a tyrant, by performing arts, by terror, by peace, by anything. But once we get into trying to find it we just forget that this small thing is of prime importance and give up to 'Maya' or the worldly desires.
Believe me a street-side vendor may not be the richest person but he might be happier than what you are right now.
So let's try to find that one thing that is the most important thing of life, Inner Happiness.
