2- Our attachments (things we like or fall in love with) become the source of our suffering because they are not permanent and sooner or later we will lose them, because nothing is permanent.
3- There is nothing wrong with loving things and other people, so long we never be mistaken that we will have them forever or we will last forever to enjoy them, because nothing is permanent.
4- Knowing the nature of universe helps us to be peaceful and to accept this nature the way it is, because the only permanent thing in this universe is impermanence.
5- We are born to be peaceful and in harmony with the universe, but we are trained to be worried , unhappy and anxious, because we are never thought about the impermanence rule and we suffer for losing or not having things or people we love.
6- The biggest journey in life is not to go and reach to anything or anywhere, the biggest journey is to come back to our real nature, the way it was pure and in harmony with universe when we were born.
