Origin
Born in Rondônia, a land of rivers
The Guaporé flows into the Mamoré; the Mamoré meets the Beni and, together, they form the Madeira, one of the largest tributaries of the Amazon. That's how we think: every idea adds to the current.

From compass rose to rose of rivers
In Portuguese, the compass rose is the “rose of the winds”. Swap the wind for the river, and only the name changes.
