Offerings serve to establish and renew relations ('contracts', 'pacts', or 'covenants') with the other world, and the choice, number, preparation, and arrangement of the offered items (such as special maize breads, maize and cacao drinks and honey liquor, flowers, incense nodules, rubber figures, and also, cigars) obey to stringent rules. In the same way, a drink made of exactly 415 grains of parched maize was to be offered to participants in a pre-Spanish New Year ritual, and on another occasion, the precise number of 49 grains of maize mixed with copal (incense) was to be burnt. A well-known example of a ritual meal is the "Holy Mass of the maize farmer" ("misa milpera") celebrated at an improvised altar for the Yucatec rain deities. Particularly Lacandon ritual was entirely focused on the 'feeding' of the deities, as represented by their incense burners.
