You are in the ICU. Death may hit you any moment. You are India's 3rd richest man. What are you thinking? Are you feeling proud of your grand success? Or are you feeling humbled by the power of God? Do you feel powerless suddenly inspite of all your worldly power?
Death does this precisely. You feel out of control. Because the curtain of the hereafter in the next world is opaque. You can't see it.
It is wisdom to think of death often. It makes you more human. It connects you to your soul. It destroys your greed, and ambitions. It helps you preserve your values. Death levels life. Think of death not only when dying, but every single day. Remember your mortality. You will become more wise.
Achievements don't matter on deathbed.
