Decline 

During the British colonial rule, there were protestant groups that worked to convert indigenous groups. The traditional Maya ceremonies, like Hetzmek, were discouraged in favor of the Christian sacraments, and for those who didn't follow, they would often be killed. 

England, Nora C. "Notes from the Field: The Death of the Dance: Cultural Change and Religious Conversion in Guatemala." Cultural Survival Quarterly, Cultural Survival, 2002, states that Protestant missionaries forbid converts from participating in activities that have ties to Maya cultural traditions. When one converts, he or she is expected to be born again, not just spiritually, but also culturally. This means giving up rituals that are connected with the Maya faith and culture that were allowed to continue under Catholicism. 

This led many Maya families to convert to Christian rituals, which led to the decline of ceremonies in certain parts of the community.

In the interview done with Mr. Tzul (2nd April 2023), he stated that prayers such as "Our Father" and "Hail Mary" suggest syncretism between indigenous and introduced beliefs, which indicates cultural adaptation through time, which leads to the decline of the traditions.
