Did Mayans sacrifice by using fire? Thanks for your help!!

Here is how the Mayan sacrificed:

The Maya Indians believed blood sacrifice kept the cosmos in balance. Women, children and men were painted blue, then sacrificed by cardiectomy; that is the removal of the heart. These ceremonies were held either at the top of the pyramids, or the temple courtyard. It was an honor to be sacrificed, as evidenced by the smiling figures in Mayan artist's representations of the ritual, as it was believed than any man, woman or child to die by their own hand or that of a Mayan Priest went immediately to Maya Paradise.
