Prayer has not to be just verbal. A verbal prayer is a pseudo phenomenon; it pretends to be prayer, but it is plastic. It is not a real flower. The real prayer has nothing to do with language at all because God understands no language.
There are three thousand languages on earth and scientists say that there are fifty thousand earths existing with life on them. You can just imagine God going mad; he has to understand so many languages. God understands only one language and the name of that language is silence.
Silence is neither German nor English nor French. Anybody who falls into silence is no longer part of any nationality, any linguistic group, any race, any religion. Silence knows no boundaries, it is infinite; and to be in silence is to be in prayer.
