Impermanence

The only thing that is permanent is God. All other things will eventually become dust and less than a memory. It is important to reflect on this whenever I feel the desire for praise or fame of any sort. Even famous important worldly people are quickly forgotten. After my bones are dust nobody left will remember me. Even if some do, when they are dust who will be left to remember? Earth too, and the universe, both will not last. With Vaheguroo's Kirpa I hope to attach myself to the only permanent thing.

The body is not permanent, neither are our possessions. Everything can be lost in an instant, just like how the tsunami victims lost everything. We never know when it might happen. It could be a beautiful day without a cloud in the sky and then everything could be washed away.

Saarang, Ninth Mehl:
O mortal, why have you wasted your life?
Intoxicated with Maya and its riches, involved in corrupt pleasures, you have not sought the Sanctuary of the Lord. ||1||Pause||
This whole world is just a dream; why does seeing it fill you with greed?
Everything that has been created will be destroyed; nothing will remain. ||1||
You see this false body as true; in this way, you have placed yourself in bondage.
O servant Nanak, he is a liberated being, whose consciousness lovingly vibrates, and meditates on the Lord. ||2||3||
-Guru Tegh Bahaadur Ji on Pannaa 1231.

This world is a wall of sand, it will not endure.
