According to acclaimed Xicanx playwright Luis Valdez "In Lak’Ech is a timeless Mayan precept he incorporated into a larger poem called “Pensamiento Serpentino.” More specifically, I inherited In Lak’Ech directly from the late Professor Domingo Martinez Paredes of the National University of Mexico in the 1970s. He was the renowned author of several books on Mayan thought and culture, and I had the privilege of being personally tutored by him. The meaning of the phrase is affiliated with the Mayan definition of the human being, which they called “huinik’lil” or “vibrant being.” In this regard, we are all part of the same universal vibration." In Lak'Ech translates to Tu eres mi otro yo or you are my other me.
