It is highly unlikely that one can. Truly, indeed, experience cannot be captured by language. Often enough language creates misunderstandings. Many times there is a confusion about the meaning of what a person is saying. People say things they don't mean, mean things they don't say, say too much and babble on.
Actions always speak louder than words.
A person can say that he loves someone but if his actions don't demonstrate love then there will be doubt as to whether or not the love truly does exist. Sometimes language can't convey understanding, many times there are not words for understanding. Understanding is also an experience and like all experiences, understanding can't be communicated all the time. One is understood when others grasp the meaning he or she intended to communicate. There are many languages throughout the world and throughout history.
