There is no tree in the tiny acorn, but there is the ever-persistent idea of a tree. The acorn cannot move on its own, or ask for help, or even think for itself, but it can hold on to that idea, and it does.
When the tiny acorn becomes overwhelmed and buried by its surroundings, it then begins to express the idea. It does not complain or wish for more, but makes use of what it has to promote and manifest the idea, the idea of a tree that it holds in its every fibre.
When the thunderous storms come, it does not fear them or hide from them, but uses them to continue expressing the idea it holds of a mighty tree. When the scorching sun beats down, the acorn takes that energy and puts it to productive use, transforming its idea into reality.
And little by little, cell by cell, the idea of a tree begins to become a tree. The hardships and challenges come, yet that idea persists and the tree that is its object grows bigger and ever stronger.
The idea in the acorn becomes a magnificent oak tree. It does so using only the resources which happen to come to it.
You have a big advantage over the acorn, for you can think, you can learn, you can move yourself and other things around. Just imagine, then, how even more magnificently you can express your own dreams and ideas, making positive use of whatever may come your way
