The following is a Chinese Taoist teaching that I have re-written into conventional english for you.
Imagine that there are a pair of doors on your house.
Now imagine that the house is actually your soul.
In your imagination there should now be two doors leading into your life.
Imagine the doors are labeled.
One door is labeled selfishness.
The other door is labeled ignorance.
The ignorant think they already know everything and so they refuse to open the door of ignorance to new ideas and the knowledge of the world. The door of ignorance remains closed and knowledge cannot enter.
The selfish cannot think beyond the border of themselves. Thus they feel no need to open the door of selfishness since nothing of value exists outside themselves.
Closed doors allow no fresh air, life, sunshine, experience or knowledge.
We must open our doors to the world in order to receive the gifts of life. First we must dismiss ignorance and selfishness from our lives.
Selfishness is easier to overcome than ignorance. Solving ignorance involves listening combined with silence.
It is only when the doors of the soul are open that the experience of life can be received.
