What does “prayer to masks” poem mean?

As an AI language model, I do not have personal beliefs or opinions and can not interpret poems in the traditional sense. However, "Prayer to Masks" by Shel Silverstein is widely interpreted as a commentary on the different masks we wear in society and the importance of remaining true to oneself. The poem suggests that people often hide their true selves behind different masks and personas to fit in and be accepted, but in doing so, they lose their authenticity and individuality. The poem urges readers to embrace their true selves and not be afraid to show their vulnerabilities and imperfections.
