The theory of "Torah for its own sake" should be explained here. This is a theory which I agree with. It is that Learning Torah [i.e. the Old Testament and the Talmud-or as it is known the Oral and written law] is a mitzvah of prime importance. I personally feel there is a objective reality behind this idea. That means I do not think this reality depends on the subject. This is like when I say something is yellow. I also mean it is objectivity yellow and does not depend on who is looking at it. This is how I look at the Torah and the Talmud.--as objectively holy. and not dependent on who is reading them.
Torah, I feel, should have two effects. One is character correction, and the other attachment with the Divine. Often we find these two effects are not present.
Now as for the idea of learning Torah for its own sake. This ideal is built on statements in the Talmud and on this idea of learning Torah as being the highest service of God that one can aspire to. In this world view it is proper to trust in God and to learn Torah all day long and to depend on the idea that God will provide for ones needs.
However it does not mean that one depends on charity or on extorting the State of Israel to pay for this activity. It further does not imply shirking ones obligation to his community as in serving in the IDF.
[Now why should Torah learning have these desired effect you might ask: Character correction and devekut?
Because holiness is intimately connected with character. If you see a person with bad character you can bet that he is not connected in any way to anything Divine. If you see someone you think is a tzadik--does miracles etc, but has bad traits then you can bet that his powers comes from the Intermediate Zone or perhaps even the three prime kelipot--the dark side.]
