The Kolla spiritual world resembles the Aymara's.
Their main ancestral beliefs relate to the Pachamama, mother earth, life giver and organizer of human's life. She knows when, how and why things ought to be the way they are.
Ceremonies for curing illnesses and for petitioning are conducted by a yatiri, a wise person chosen by the spiritual forces, and whose designation has been communicated in a dream.
Rituals for the community sustenance and welfare are performed on the hills, at the highest altitudes.
An important date in the Kolla calendar, as it is among other indigenous people, is June 23, the winter solstice that announces the agricultural New Year.
