While basic faith is important some prayer also, but still I have seen people that think the reason they do not get their problems solved is from lack of faith or prayer. My approach is rather to learn Torah--the word of God, to seek God, and then all good things will come to one. But my approach to learning Torah is a bit different from way the Lithuanian yeshiva world understands it. For as per the Rambam, I include Physics and Metaphysics along with the Oral and Written Law.
[Take philosophy out of the set and you end up with fanatic ideology. Thinking comes before believing because belief is nothing else than thinking with agreement.]
The trouble is the Jewish religious world is solely that of fanaticism. Even the groups which are apparently are moderate are simply moderate as a result of being fanatic about moderation. Their moderation is just as sick.
Most of the writings in the religious world are placebo religion.[Plecebo is the sugar pill you give to a patient that they believe is a real pill and it in fact makes them feel better.]
In placebo religion all the benefit comes from the belief of the believer. Not surprisingly there are psychological benefits, just like there are with a placebo pill, but there is no evidence that there's any spiritual benefit in the writing itself. For example, there is no evidence that in it there is an 'absolute Truth' or that finding it will lead to some sort of miraculous change in one's life. Without belief a placebo religion, just like a placebo pill, has nothing substantial to offer. And to offer placebo religion as though there's something substantial in it is clearly deceptive and immoral.
Frankly I think pretty much or all religious writings is all placebo pills that make people feel good and holy without having any real benefit, spiritual or otherwise. I do not deny that most religious writings make people feel good--very good and part of their group just like the sugar pill gives real positive effects when people believe in it. But in the long run it is a lie.
However the basic set of the Tenach and Two Talmuds with the Halachic and Agadic midrashim with the rishonim I believe to be of real objective benefit. Sola scriptura sola talmuda. אין לנו אלא דינא דגמרא ("We only have the law of the Gemara.") [That is a statement from Reb Chaim from Voloshin a disciple of the Gra. But it is obvious to anyone whose has learned any poskim [legal authorities] at all. All poskim [legal authorities] without exception are looking for דינא דגמרא (law of the Gemara). For example the Magen Avraham, Shach Taz, חלקת מחוקק,
בית שמואל ר'עא ונתיבות etc. always look for (law of the Gemara) דינא דגמרא. If that is how the Shulchan Aruch come out then fine. But if not then they have no trouble throwing out the decision of the Beit Joseph in the Shulchan Aruch and going by the Gemara.
