7.429

法爾道理中，云成立法性者，如四大性堅濕煗動非因緣依，性自成立。難思法性者，不應思惟地何故堅而不是濕等。安住法性者，有佛無佛地常堅等。

Under the principle of the nature of things (dharmatā-yukti): regarding "established dharmatā," as the natures of the four great elements—solidity, moisture, heat, and motility—do not depend on causes and conditions, their nature is intrinsically established. Regarding "inconceivable dharmatā," one should not deliberate on why earth is solid rather than moist, and so forth. Regarding "steadfastly abiding dharmatā," whether Buddhas exist or do not exist, earth is constantly solid, and so forth.
