Three coca leaves are known as the sacred k'intu  symbolizing integration of body, mind and heart. Such a k'intu is frequently placed under the mesa cloths of some Peruvian curanderos when consecrating the  altar ground. 

Mama Killa was known as Mother Moon, and was goddess of the moon. According to Father Bernabe Cobo, writing in the mid-sixteenth century, the moon was worshiped because of her admirable beauty and the benefits she bestows upon the world. She was important for calculating the passage of time and the calendar, due to the fact that many rituals were based upon the lunar calendar and adjusted to match the solar year. She also oversaw marriage, women's menstrual cycles and was deemed the protector of women in general.  Source: Wikipedia contributors. Mama Killa. Wikipedia, The Free Encyclopedia.
