"大寺院男住持" can be translated as "the male abbot of a large temple" or "the male head monk of a major monastery".
Here, “大寺院” is rendered as "a large temple" or "a major monastery", depending on the context and the specific type of Buddhist institution being referred to. “男住持” is translated as "the male abbot" or "the male head monk", where "abbot" typically refers to the superior of a monastery or abbey in some Christian traditions but is also used in some contexts to refer to the head of a Buddhist monastery, while "head monk" is a more straightforward and universally understandable term.
