The only reason some persons are unhappy is the habit or nature of expecting others to care for their contribute towards happiness.
We want everything and all in our surroundings to work for our happiness.
We want everybody around us to be truthful. We want our children to be truthful but ask them to convey that dad is not at home if we are not in mood to answer the phone.
We go to educational institutions but do not want knowledge we just want the employers to pay accordingly. When we are expected to work hard, we don’t want to work but we argue, “What is the value of my qualification if I have to toil?”
And we are aware about this, we also would like to change this but either do not have the time or the compulsion.
Also, we will not tolerate somebody else informing us about this malady because we are comfortable with the ‘current’, because we are convinced that it works and the change, the opposite, the better will not.
The verse in Sanskrut says:
chinnam chinnam punarapi punah svadu chaivekshu-kandam
dagdham dagdham punarapi punah kanchanam kanta-varnam
pranante’pi prakriti-vikritir jayate nottamanam
“Again and again you rub the sandalwood on the stone, it produces only a fragrant paste. Cut the sugar cane again and again, it provides only sweetness. Burn again and again a piece of gold, it always shines. In the same way, when noble people are put into different situations, they do not change.”
