Aymaras conceive their world as a space in which East or Orient is "In Front Of". Temples and houses must be oriented towards the east. It is the beginning of water and life. Sun and rains are also born there, referred to as the Cultivating Deity. Middle is valley and rivulets, is called "Near or Here".
West or Occident is "Under or Behind". This is where water is forbidden or vegetation ends; it is the desert. It is also the place where the dead go.
Viracocha went there, the Andean Cultivator, the Creator God, who went to the Grand Cocha (Pacific Ocean), after he finished creation.
These are the three Aymara spiritual areas.
Arajpacha symbolizes light and life. Towards the East.
Manquepacha symbolizes death and darkness. Towards the West.
And Akapacha it is the space between heaven and hell or between life and death, It is the center where the Aymara live.
The concept of Tinku deals with the balance and reciprocity between the community and those areas. (Tinku comes from Tincuy verb; to match, to equilibrate, to adapt.) The Aymara follow Tinku between Arajpacha and Manquepacha. They try to live in harmony, striving to reach the wisdom of Akapacha without going to any extremes.
