In Buddhist practice, it is said that while samatha meditation can calm the mind, only vipassana meditation can reveal how the mind was disturbed to start with, which is what leads to insight knowledge (jnana; Pali nana) and understanding (prajna Pali panna), and thus can lead to nirvana (Pali nibbana). When one is in jhana, all defilements are suppressed temporarily. Only understanding (prajna or vipassana) eradicates the defilements completely. Jhanas are also states that Arahants abide in order to rest.

Through the force of sheer numbers, the English-speaking American settlers entering the Southwest established their language, culture, and law as dominant, to the extent it fully displaced Spanish in the public sphere; this is why the United States never developed bilingualism as Canada did. For example, the California constitutional convention of 1849 had eight Californio participants; the resulting state constitution was produced in English and Spanish, and it contained a clause requiring all published laws and regulations to be published in both languages. The constitutional convention of 1872 had no Spanish-speaking participants; the convention's English-speaking participants felt that the state's remaining minority of Spanish-speakers should simply learn English; and the convention ultimately voted 46-39 to revise the earlier clause so that all official proceedings would henceforth be published only in English.

Why isn't the southwest Spanish speaking?

Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.

What compromises mainly preventative measures?
Answer:
computer security
