The relational mindfulness project is strongly based on the perspective of relational being of social constructionism, as an alternative to the conceptions of self, anchored in romantic self and mechanical self. It questions the modern traditional understanding, according to which mindfulness is translated/interpreted to a framing of individual mind, of the disengaged self. By questioning the idea of ​​a substantial, prior, internal self, relational perspective converges with the position of an incarnate self, not only in the body but for the same reason, situated in the world with others. From that view, identity is not understood as equivalent to themselves, but rather the identity is presented as a construction, socially embodied in a consensual contextual domain subject to conventions. It is in this sense that the approaches of social constructionism meet the tradition of relational Buddhism from which mindfulness emerges, which points to the notion of non-I. When applying modern framing, it would be understood as an absence of self-structure to be. Viewed from the incarnate relational vision, it is understood as a position of a relational, non-substantial self. In the context of discussion about identity, distinguishing between different discourses of the self, we emphasize reflection on the meta-theoretical assumptions. Delimiting the true and opening the conversation in a convergence between indeterminacy from social constructionism and the foundations of relational mindfulness, we are interested in reflecting on the assumptions in a spirit of conversation between vocabularies of the self, rather than in the epistemological confrontation and paradigms. From this position, being in the world with others implies a vision of the interbeing. Therefore, a new and coherent basis of mindfulness appears as relational, allowing mindfulness and the vision of the human future to be reconciled, placing it as a practice in contact with others.
