In Paulo Coelho's The Alchemist, what is meant by the "language of the world?"

In Coelho's
, the language of the world is the way all things communicate because all
things are one. Santiago tries to tell the Englishman this. In his turn, the Englishman tells
Santiago that all he needs is found in books; but the Englishman finds nothing important in
trying to listen to the desert or by searching for omens. Likewise, Santiago learns nothing from
the Englishman's books. However, Santiago does not dismiss the Englishman's way of learning: he
only knows that he cannot learn to communicate with the world in that
way

"Everyone has his or her own way of learning
things," he said to himself. "[The Englishman's] way isnt the same as mine, nor mine
as his. But were both in search of our Personal Legends, and I respect him for
that."

So both men continue on their quest to
discover their Personal Legend. The more Santiago looks, the easier it becomes to recognize
omens. He develops a kinship with nature and can read the signs it shares with one who is
observant.

The language of the world manifests itself in several ways. During
the account of the boy's journey, we find that he understands the language of the world based on
one's response to the world:

There was a language in the
world that everyone understood€¦It was the language of enthusiasm, of things accomplished with
love and purpose, and as part of a search for something believed in and desired.

In the desert, the alchemist describes the relationship Santiago
must develop with nature, and in so doing, understand the language of the world:

You dont even have to understand the desert: all you have to do is
contemplate a simple grain of sand, and you will see in it all the marvels of creation€¦Listen
to your heart.  It knows all things, because it came from the Soul of the World...

So the heart knows the language of the world. It is
also found in nature. 

The chief of a military camp
takes the alchemist and Santiago captive. The only way the boy can escape death is to prove that
he has great powera power of which Santiago knows nothing. However, in the spirit of sink or
swim, Santiago speaks with the wind, the sun and the desert; and finally he
communicates (without words) with the Soul of the World (the Hand That
Wrote All)listening with his heart. It is in these discussions that
Santiago learns how to move himself with the wind's help.

The language of the
world is also present in the instantaneous understanding that Santiago and Fatima
have:

It was the pure Language of the World...What the
boy felt at that moment was that he was in the presence of the only woman in his life, and that,
with no need for words, she recognized the same thing.

Because we are all connected, we are not only made of the same
stuff, but we can also communicate with nature if, as Santiago tells the
Englishman, we listen to nature speaking to us. In
this regard, we should also, then, be able to speak to one another regardless of where we come
from, which Santiago discovers in being able to understand people who do not speak his
native language.

The language of the world refers to the
oneness of all things: that everything in the universe is tied together.
And believers of this truth feel that the language of the universe links
people to the world and to each other.
