I have been thinking about the problems in the world and i recall the advice that i heard while in Litvak yeshivot-- learning Torah brings peace to the world.  Instead of complaining about it or offering solutions that will not work, I  recommend to people to learn Torah. But "Torah" is specific. It is not a word that can be applied to anything. As the Rambam wrote in a letter: "Just like one can not add or subtract from the Written Law, so one can not add or subtract from the Oral Law." That is: the only things which get to be called the Oral Law are the actual books handed down by the sages of the Mishna and Talmud. Later on books are not "Torah" except in a secondhand sort of way in that some of them might be explanations of the Talmud.    

The sad thing is I wanted to learn Torah , but circumstances and my own personal failings led to me not being able to do so, so I had to depend on the opinion of some Rishonim like the Rambam that include Physics and Metaphysics in the category of Learning Torah. [Not that he is saying they are Torah, but rather in the category of ''learning Torah'' that is to clarify the deeper meaning of Torah.]
