Yanantin
Yanantin (Wechua: yanantin, "complementary pair" or "that which is paired") is a foundational concept in Wechua cosmology expressing the principle that existence comprises complementary dualities in dynamic balance. Unlike dualistic systems that frame opposites as conflicting, yanantin holds that apparent opposites are mutually necessary, each incomplete without its complement. The Sun (Inti) and Moon (Killa), male and female, mountain and valley, hanan pacha (upper world) and ukhu pacha (inner world): all exist as paired forces whose interaction sustains the cosmos. The concept is closely related to tinkuy, which denotes the sacred points and moments where complementary forces meet.
Yanantin informs Wechua understandings of social organization, agriculture, and gender. The ayllu system traditionally divided communities into complementary moieties with paired responsibilities. Marriage unites qhari (man) and warmi (woman) as complementary partners. Within this framework, individuals who exist between or outside the male-female binary, known as chawpi runakuna ("people of the center"), are understood as embodying tinkuy, the meeting point of complementary forces. The quariwarmi tradition of ritual specialists with combined gender expression derives directly from this cosmological understanding. Yanantin remains central to Wechua cultural identity and has influenced broader New Alexandrian attitudes toward gender diversity.
