WHAT IS THE POISON TREE?
The poison tree, the narrative of whose growth we have given from the sowing of the seed to the production of its fruit, is to be found in every house.

Its seed is sown in every field.

There is no human being, however wise, whose heart is not touched by the passions of anger, envy, and desire.

Some are able to subdue their passions as they arise; these are great men.

Others have not this power, and here the poison tree springs up.
