Imagine that everyone in the world got $1000 to spend. It would be used to do a variety of things. Some would chose to go out and party all night. Some might just deposit it in their bank and forget about it. Some might invest it on a child's future while others might decide to donate it to a worthwhile charity. Some might repay a portion of a loan while some might finally afford basic necessities or have a proper meal.
We label some actions as good, some as wasteful and perhaps some as bad based on an elaborate value system devised over time. However, the essence is that everyone got the same $1000. Most of our time above was spent looking at actions, rather than the basic fact that everyone got some money. Even focusing on the amount of money, or money itself distracts from the essence that everyone got something.
We all really have only one currency and that is time. People do all sorts of things with their time - they serve or laze, entertain or bore, create or steal. Debating about how a person uses his time again drifts from this essence. Everyone just spends time being and doing.
What people do with their time has been the basis of all judgments. It has been ruminated on for centuries. All laws, rules, values, morals and ethics are based on what people should do with their time. There is already enough attention and awareness towards this concept.
For a few minutes though, experience this essence instead - the basis of all existence, this absolute time, free from all judgments.
That is Shiva and experiencing it is meditation.
