This research responds to the urgency to disrupt patterns of social injustice, exclusion, and cultural genocide while promoting positive identity formation, pride, and resilience for Indigenous autistics in the post-secondary education system. This study utilized a participatory action research approach positioning participants as collaborators with the research team. Data collection involved qualitative data derived from the transcripts of online sessions, participant digital stories, and a summative survey. Thematic analysis was used to identify emergent themes of individual and a collective narrative. Findings are presented as an original concept of the author called Thrivival: The Fire Within, comprising four themes: self-identity, time, balance, and community. This work contributes to a broader understanding and expressions of Indigenization, decolonization, equity, diversity, and inclusion in post-secondary teaching, learning, and policy to better support the identity and success of Indigenous autistic students and arguably, all students who experience intersectional discrimination within post-secondary education systems.
