The Tao is like a well: used but never used up.
The Tao is called the Great Mother: empty yet inexhaustible.
I am different from ordinary people. I drink from the Great Mother's breasts.
(Tao Te Ching)
There once was a baby that was breastfed for seven years. When the baby had grown into a big sturdy boy, his mother told him to go up to the mountains and see whether he could withstand the mountain storms. He tried his best, but after a few seconds a strong breeze swept him off his feet.
He went back to his mom and she breast-fed him for another seven years. And when he was a sturdy teenager his mother asked him to go up the mountains to test the winds one more time. A storm was howling furiously and the teenager tried his best to keep his balance. He had his legs stamped into the ground, but after ten minutes his tired legs gave into the pressure and he fell to the ground yet again.
He returned to his mom and she breast-fed him for another seven years. When he had grown into a strong and handsome man he went up to the mountain and only laughed at the mountain winds. He became a soldier and destroyed whole armies with his strength, sturdiness and apparent invincibility. You don't have to strive and you don't have to fear. The only thing you have to do is to let Mother Nature - the Tao - nourish you. So-called setbacks are nothing but divine interventions to launch you on a higher path. Maintain your connection with the Tao and everything is being taken care of.
