When you look at Jewish mysticism which acts as umbrella that covers a vast range of theories regarding beliefs, practices, Godhead, all of which reaches far beyond standard Judaism requirements. When you look at particular at Kabbalah which is a Jewish mystic variety arising in 12th century CE in Catalonia and Provence.
It is a distinct phenomenon arising from Ashkenazic and through interpretation applied to Jewish text as they continue to try decipher the meaning of certain words and sayings. The Hebrew language has divine origin according to Jewish belief and tradition as they believe God used this very language when he pronounced His will. Thus do it possess creative potential beyond belief and this is where the magical and mystical traditions stem from within the Jewish communities.
The oldest or one of the oldest is sefer yetsirah which dates back to the second and seventh centuries CE, where it is said the creation process took place through ten cardinal numbers and the twenty two letters of the Hebrew language. Using this language through manipulation and divine process could they create a golem. A golem is said to be able to control its body and animate and when you name a golem the creature could be annihilated.
Now looking at mystical tradition you find a designated object and its name are linked directly in order that the object is reflected by name. An entity possess both a name and a linguistic equivalents, angels and divine beings as well as God Himself are no exception in some Kabbalah. You will find reference and interpretations in early Jewish text of both angelic and divine names and the knowledge is known by true Jews who believe in the Kabbalah to obtain special powers when they are both capable and worthy of having them.
While not always openly introduced or even believed by various Jews it remains an aspect of torah, which means instructions or guidance. When you learn to appreciate Kabbalah it relates to life instruction and it acts as practical guidance and direction too. As soon as a student f kabbalah understands it they will understand the divine presence of infinite light and understand cosmic dimensions by believing everything and all have meaning with nothing trivial in life.
