Do we get what we want ? Let us analyze one by one. First of all Life. We want life, we want to leave as long as possible But we get the opposite that is Death. Secondly we always more and more Knowledge let the knowledge be of any type. If we would have got the Real knowledge then our knowledge, our intelligence must be in saturated form, we must be satisfied with what we have with us. No, we are not satisfied we rather look for more 'n' more knowledge available around us. In other words we do not get the required knowledge. Lastly, Happiness Do we get the happiness we actually want ? If we would have got the real happiness then we must be satisfied with that. For example :- Let one person finds happiness in eating sweets. Let, I will give him his favorite sweet to eat he will have it and say 'I'm loving It', then I will give him another one He will say 'Yes, it was awesome', again I will offer another one He will say 'It was good'. Again another one 'No, Its enough'. You observe the thing from which the person was getting happiness is No more getting happiness from the same. Rather his happiness decreases. The Knowledge and happiness we get from the World is limited with amount and time. So everything we want in our life, is either limited or we get opposite of it.
