This paper examines an indigenous complex of ideas about illnesses, misfortunes and trances in relation to the concept of ‘intercorporeality’, as discussed by Weiss and Waldby. Intercorporeality helps us understand some Nayaka senses of batha, and sheds light on the relational nuances of this indigenous notion. Batha suggests another rendition of intercorporeality, which does not pluralise the individual's ‘inside’ as a composite embodiment of exterior relations, classes and hierarchies. Rather, this indigenous category underscores the sense of an irreducible plurality of ‘relatives’, each joined to all the others, constituting a web of mutualities that transcend classes and boundaries, including even human/non-human.
