Abstract

Indigenous psychologies are informed by their cosmogonies and cosmologies, philosophies, spirituality and religions, traditions and customs, and knowledge and praxis systems. This paper reviews some conceptions of consciousness, psyche, spirit, mental and physical health, relations to all Earth Beings (human and nonhuman), ancestors, nature, and altered states of consciousness among the Nahua and Maya of Mexico. Colonization has threatened these rich legacies by imposing the conquerors' cosmologies. However, these Indigenous communities continue to use plants, mushrooms, and some animals to generate altered states of consciousness, enacting sacred rituals and healing. The conclusion recommends learning from these knowledge and praxes systems and their related consciousness and spiritual states to expand the emergence of decolonial psychology that may offer alternatives to address the challenges of our time.
