The phrase that is translated as “with all your heart, and with all your soul, and with all your mind” in English versions is rendered in Kahua with a term for belly/chest as the seat of the emotions.
The same phrase is translated into Kuy as “with all your heart-liver”to show the totality of one’s being. (Source: David Clark)
The whole phrase is translated in Tboli as “cause it to start from the very beginning of your stomach your loving God, for he is your place of holding.”
In Poqomchi’ (as in many other Mayan languages), the term “heart” covers both “heart” and “mind.”
