The Incan kings divided their empire in four parts called “Suyos” and put as the center point the City of Cusco which in Quechua (a native language) means navel of the earth. They called it the navel because all of Peru is long and skinny like a human body and this city is located almost exactly in the middle. (Inca Garcilazo de la Vega)

Tawantisuyu in Quechua means the four terrains of sun- “Tawa”: four “Inti”: sun “Suyu”: terrain
The four terrains were:

1.Chinchaysuyu
2. Kontisuyu
3. Kollasuyu
4. Antisuyu

There were 18 Incas that governed the empire: Manco Capac, Sinchi Roca, Lloque Yupanqui, Mayta Cápac, Cápac Yupanqui, Inca Roca, Yahuar Huácac, Viracocha Inca. The epic of splendor was between the years of 1430 and 1525 with three Incas: Pachakutek Inca Yupanqui, Tupac Inca Yupanqui (son) and Huayana Cápac (grandchild) the empire grew through their conquests and embellished itself through its works of acrhitecture and its engineering masters. This epic was considered the golden century for the empire.
Later came Huáscar, Atahualpa and finally after the European invasion of 1532 came Manco Inca and Paullu Inca.

Endowed with an incredible power of stellar phenomenon called Solisticios and Equinoccios and having been the precursors of cosmic travel through altered states of consciences, and through consumption of San Pedro and Ayahuasca, they succeeded in forming an empire and creating the crystal city of Machu Piccu. Also, they were able to raise their ceremonial centers in energetic vertices also called Ceques and in their places of convergence they raised electromagnetic centers called Huacas.

Through these visions they constructed ceremonial temples with dimensional doors having their force and inspiration be their god Wiracocha, the sun god, by him they were sons of light, sons of god.
It is clear hat the man had lost his irrationality understanding not so much by chaos or by disorder, or thought as to which we are accustomed but by irrational thought which embraces:

Intuition
The development of subtle qualities

The connection with other laws that govern other worlds, these other worlds that are inside of this one. Human beings have lost contact with the other polarity, which is necessary for any other existence and for life itself. Fortunately there remain small islands formed by mean called shamans that maintain the torch of this knowledge.

The word shaman comes from: “sa”: to know and “man”: man. There exists a real possibility for an interaction between the principles of modern science and the acts carried out by the Incan culture. What we call consciousness consists of waves of information that move from the spirit to the matter and return to the spirit. The shaman ceremonies provoke a mental and corporal state that allows one to see how this information comes from the spirit and how it acts over the matter, giving way to the profound understandings that are the origin of evolutionary processes.
