Time and karma
When a bird is alive, it eats ants
When the bird has died, ants eat it
One tree can be made into a million matchsticks but only one matchstick is needed to burn a million trees .
Circumstances can change at anytime
Don't devalue or hurt anyone in this life. You may be powerful today, but time is more powerful than you.
If you give a good thing to the world, then over time your karma will be good, and you'll receive good.
I believe in Karma. If the good is sown, the good is collected. When positive things are made, that returns well.
