Final answer:
The concept of monks sleeping in coffins relates to Christian ascetic practices of meditating on death as a form of spiritual discipline. The text does not specifically confirm Mary Jane's stance on this, but it is implied to connect with the themes of asceticism and the temporary nature of life. Mr. Browne's confusion could hint at a different religious background without such traditions.
Step-by-step explanation:
The discussion in the text seems to revolve around the practices of asceticism and memento mori in monastic life. It isn’t particularly clear from the excerpts provided whether Mary Jane specifically mentions monks sleeping in coffins; however, given the context, it can be inferred that the supposed practice would align with the theme of meditation on death — a practice rooted in the Christian tradition of memento mori, reflecting on the temporary nature of earthly life and the importance of focusing on the eternal life to come.
This theme is deeply intertwined with the overall narrative of monks and Christian ascetism, where the renouncement of worldly comforts and constant meditation on spiritual things (including death) was common.
However, the excerpts do not provide any direct reference to Mary Jane's explanation or any explicit connection with Mr. Brown’s religious background. Typically, discussions on historical monastic practices involve the understanding of monks participating in various forms of austerity to enhance their spiritual discipline.
This would often include practices aimed towards humility and constant remembrance of mortality, as a means to detach from worldly desires and focus on spiritual growth.
The concept of sleeping in coffins, true or rumored, might symbolize this detachment and the preparation for the afterlife. Mr. Browne's confusion might stem from a different religious upbringing that may not place as much emphasis on physical displays of penance or contemplation of death.
Monks seeking to reflect on mortality might potentially use the symbol of a coffin, though it's more likely a metaphorical concept rather than a literal practice in historical context.
