The shamanism is a way to perceive the world and to interact with it. It's a spiritual path, a model of life, a total fusion with the universe. It is the ability to coexist by instinct with nature, so that the global harmony is balance.
The flow of energy that pass through in the human conscious, runs also through animals, plants and minerals. All those flows of energies, can integrate themselves with harmony one to the others, and this way widen our universe. All that lives is link together and nothing stand or sustain by itself.
I think that the truth rest in the spirit, and that shamanism is one of those different techniques to access the spirit. A shaman can communicate with the body of animals and the energy flow. He/she can help this animal to restore the balance between body and spirit.
What is contain by us as humans, was contain by others before us and will be contain by others after us in the future, as long as there will be life on earth. We are all connected one to the other in a certain way.
As example: We received from our ancestors a genetic that we did transmit and talents that we did improve and pass on to our descents. This cycle will continue as long as there will be life.
The shaman see the earth, the humans, the animals as parts of a total entity in evolution. We can find shaman in almost all cultures in the world.
The time of isolation permit the shaman to maintain communication with his/her own unconscious to know himself/herself better and stay center. Well center he/she cannot be drag in chaos and can help his fellow humans and animals.
In our contemporary society, the need to pass time alone is not always well understood, because social activities are very much valorized. All humans need solitude, to evaluate themselves and better center their inside to progress positively.
The shaman spiritual path by its holistic approach, express itself in an essential union of the spirit and the body. The shamanism is not a medicine nor a religion, it's a spiritual path which teaches how to blend with the complete universe. This spiritual path permit me a deep communication with animals around me, and make me access their essential energy.
