Meaning of "Jinba Ittai" by Zao

The song delves into themes of existence, connection, and mortality. The speaker acknowledges the complex web of relationships that define their existence, from feeling their children's breath to sharing their brother's blood. The lyrics suggest a sense of entrapment within the physical body, referred to as the "flesh machine," which serves as a vessel for consciousness. The promise of safety offered by this bodily existence is juxtaposed with the futility of trying to escape the limitations of physical form. The mention of "mouths of our graves" singing songs of unknown places implies a mysterious afterlife or beyond, contrasting with the struggles of earthly life. Ultimately, the speaker contemplates the inevitability of death as a necessary separation from the physical world and a transformation into something beyond.
