無謂，戒止之辭。倒覆，崩墜也。天地雖大，亦緣集之法，容可傾覆；以性空故，亦即清寧。千門異說不出宗意。

"Do not call" is a phrase of admonition and prohibition. "Overturned" means collapsing and falling. Although heaven and earth are vast, they are also dharmas gathered by conditions and can indeed collapse; because their nature is empty, they are also tranquil and serene. A thousand approaches and various explanations do not go beyond the doctrinal intent.
