One can lead a life of either being the cause or the effect.
The smart among us become the cause for what is happening around them.
Others follow and lead a simple life of "Effect".
Last week I attended a workshop by Br. Rashid Gazzali to the Al-Abeer Sign Lead 2020 scholars. Br. Gazzali practically showed several examples of how difficult it is to break the barrier and being the "cause".
When he asked the scholars to clap as followers they all did it enthusiastically. But when they were asked to design a unique clapping style they all experienced how difficult it is to be a cause even in simple cases like designing a clapping style!
