Here are some quotations from the chinese classic which I think are good food for thought,garnished with law of attraction and breathing techniques.
When one is out of life, one is in death.The companions of life are thirteen;the companions of death are thirteen; and when a living person moves into the realm of death,his companions are also thirteen.How is this? Becouse he draws upon the resources of life too heavily.
It is said that he who knows well how to live meets no tigers or wild buffaloes on his road, and comes out of the battle-ground untouched by the weapons of war.For in him, a buffalo would find no butt for his horns, a tiger nothing to lay his claws upon, and a weapon of war no place to admit its point. How is this? Becouse there is no room for death in him.
One who is steeped in virtue is akin to the newborn babe. wasps and poisonous serpents do not sting it, nor fierce beasts seize it, nor birds of prey maul it. Its bones are tender,its sinews soft,but its grip is firm. It has not known the union of the male and the female,growing in its wholeness,and keeping its vitality in its perfect integrity.IT howls and screams all day long without getting hoarse,becouse it embodies perfect harmony.
To know harmony is to know the Changeless.
To know the Changeless is to have insight.
To hasten the growth of life is ominous.
To control the breath by the will is to overstrain it.
To be overgrown is to decay.All this is against Tao, and whatever is against Tao soon ceases to be.

Do realize that there are lots of translations for these statements. What number are they?

I prefer Stephen Mitchell's translation but they all speak to the core of our being.

Hi Alain
The book that I have is from Shambala dragon editions, and translated by John C.H.Wu
These quotations are number 50 and 55.
My humble interpretation of the sentence on breathing is, that seen in the context of a taoist sage, who probably mastered breathing techniques since he was a toddler. He did not need to 'control' by the will for proper breathing, becouse it was done automatically.
