Life is fleeting. It goes away even before we know it.
And all the while we keep worrying about what future holds for us. One after another year passes, and we keep waiting for the next one.
Then we die.
Life is temporary. Living for the future is like chasing after the rainbow.
Living for the present is worshiping enjoyments of this life. Enjoying life is not bad. Living for enjoying is.
Live we should to please our Lord, the Kind, the Merciful. To be at Peace with the rest of the Creation, as they follow His Command. Attain Success.
Live we should for the the Day. When all things shall be decided. Live we must for after that. For that is true. That is for ever.
