Any Etymological Hebrew Dictionary would describe Torah as:

1- instruction, teaching.
2- the Book of Laws, the Torah.
3- the Five Books of the Torah, the Pentateuch.
4- theory, system.
5- a book containing the principles of any branch of science.

Torah literally means instruction, and does not mean law. For the word law, the Hebrew word Chuk (lit. law or decree) is used. Literarilly, Torah can also refer to the first five books of the Bible, among other things.

A modern example of the usage of the word Torah, is used in reference to the study of a particular field science. What is called Computer Science in America, would be called Computer Torah in Hebrew. Physics Torah, Biochemistry Torah, etc.

Much like a father that sets house rules, boundaries, etc. for his children and household, so does HaShem do through His Torah for instruction and teaching, and the ultimate goal of love and holiness. The Chukim (plural for laws) of HaShem, like the house rules of a father, are just a small portion/subset of the Torah, or divine instruction.

Therefore, it’s better to look at the Jewish bible not as just a set of decrees, but rather, as a divine book of instruction.Torah benefits the whole Universe. Torah is the book of instructions that contain the secret of the "Tikkun" – the fixing of the universe throught belief of the one like Moshe, King Messiah Yeshua! So, what is Torah?

a. Torah is from a Hebrew root word, an archery term meaning “to take aim, to shoot” —as in shooting an arrow to hit a target.

In his book, Our Father Abraham, Dr. Marvin Wilson explains, “The word torah, commonly translated ‘law’ derives from the verb yarah, ‘to cast, throw, shoot.’” The essence of the word Torah is to “hit the mark.” In the context of its usage, teaching or instruction is a better definition for Torah than "law." The Torah is specifically the first five books of the Bible, but because of its definition (teaching or instruction) can be applied to the entire Bible. Moses and Law of Moses are also used as a synonym for the Torah. See Mordechai / Mark 1:44; 12:26.

Mashiach reveals a deeper level in Torah, that was never revealed before. It is totally beyond the level of Torah than we now have, since it comes from the essence of Hashem.

The Torah that Moshe Rebbenu brought down from Har Sinai, gave the people of Israel the ability to reveal Kedushah, holiness, into the coarse, limited, physical world. 

Mashiach will do much more than reveal holiness; he will reveal a much deeper level in Torah, being the essence of Torah, which comes from the essence of Hashem. 

Rabbeinu (our Rabbi), Maran Yeshua Melech HaMashiach said: "Don’t misunderstand why I have come. I did not come to abolish the law of Moses or the writings of the prophets. No, I came to accomplish their purpose. …

This is Melech HaMashiach (King Messiah).
