Great message of a bird to the humans and whole world

Once upon a time there was a man who owned a garden. Once he trapped a bird that was plucking the best fruits in his garden. The bird informed him that if he was released, he would give three teachings of wisdom. He agreed and released the bird. After sitting down in a safe place where the gardener was sure not to catch him, the bird said:  ●.Do not regret the irretrievable.  ●.Don't believe in the impossible.  ● .Do not seek the unattainable. Then he laughed and continued: If you had not let me open you would have got a pearl the size of a lemon out of me…! Hearing this, the man got scared and climbed the tree to catch the bird. When he got too close, the bird flew higher and higher. The bird saw this man raving behind him and flew to the highest branch of the tree. Then he went to the edge of it. The man retreated in a frenzy. The branch broke and the bird flew away. He fell down. Hurt, he somehow got up and looked at the bird with regret: “Wisdom belongs to the prudent. The bird advised him: "Didn't I say don't regret what you didn't return"... But as soon as I was released, you came after me. “Didn't I say don't believe the impossible”… yet you thought a bird like me would have a pearl the size of a lemon… Didn't you say don't go after the unattainable..?”… yet you climb a tree to catch a bird like me… you are a fool… this is not just a bird's story. Most of us are like this..let's think for ourselves with logic..don't just listen to what people say one by one and follow it….
