Breathing in and out, we experience cyclic, concrete, and sensory relationships with plants and other species. Breathing exercises have long been a starting point for interrogating our views of ourselves in East Asian traditions. Drawing from insights from Japanese philosophy (such as the idea of bodymind, and works by Dōgen and Watsuji) and sciences (e.g., research on the microbiome), this chapter explores how breathing invites us to resist dichotomies such as cognition-emotion, human-environment, and agency-vulnerability. Being partially empty allows us to enter in relation with others, and even to welcome within ourselves diverse scents and microorganisms, from fungus to bacteria. We are breathing bodyminds, inhabited selves living through nature, continuously negotiating the diverse biotic (e.g., microbial) and abiotic (e.g., oxygen) flows that we breathe in and out. Each breath we take invites us to reflect on environmental ethics and on the spaces we share with and leave to other species within our bodyminds, and far beyond.
