in lak'ech ala k'in
maya
Yucatec Maya, "you are my other me", with ala k'in the paired response, "I am another yourself"
the philosophical reading is Domingo Martínez Parédez's, and it travelled on Luis Valdez's 1973 poem
the two part greeting is that modern crystallisation rather than an attested ancient formula
