I took this to heart a few years ago thinking that I needed to get back to Torah.
Then I noted the Rambam brings this idea in an expanded way in Laws of Repentance ch 9, where he brings the idea that "all fears" are removed from one that accepts the yoke of Torah. This is the same idea but in a more general sense.
This idea can be used by unscrupulous people that try to get money out of secular Jews. Still abusus non tolit usum. Abuse does not nullify use. And I can see that there is a great need to sit and learn Torah.
Since the really great and authentic Lithuanian kinds of Yeshivas based on the Gra are few and far and the evil yeshivas that are hot beds of the sitra achra [the Dark Side] are close and many, thus there really is no choice but to get yourself the basic set of Torah and learn at home. The most important I think is Rav Shach's Avi Ezri which contains the basic principles of how to learn and most of the basic principles of Torah.
But in case people are reading this that might need a more basic introduction: the best of introductory books I have seen are those of Rav Shimshon Refael Hirsh --that is his book, the Horev. After that The English Soncino Talmud I think is great. I am not exaggerating. The translations there are works of genius. After that the best book of Jewish Law is the Tur with the Beit Yoseph. I really loved learning that book with the Bach also.
