Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

Litvak yeshivas tend to be a mixed bag.
Litvak yeshivas tend to be a mixed bag. Not all perfect, but they have a lot of good. The main good is they introduce one to authentic Torah,- Torah as opposed to Torah of the Sitra Achra (Torah of the realm of Satan). [i had the great good fortune to have been in to great Litvak yeshivot, the Mir and Shar Yashuv]
But if you realize from where the good energy of the great yeshivas derives from--the Gra, you ought to be able to bypass any institution and simply work on Torah yourself with the need of any group.--Just by following the path of the Gra yourself.
The trouble seems to be that they really do not follow the Gra fully--which anyway I understand can be hard to do. After all the signature on the letter of excommunication is a start. Next would be the individual to get through the two Talmuds with Tosphot, Pnei Moshe, Maharsha and the two sets of midrashim, legal and agadic.][I would also add the Hidushim of Rav Chaim of Brisk and the Avi Ezri of Rav Shach.
much later note: even though rav shach's avi ezri is the best, i would still try to get the great roshei yeshivot of the litvak world, the books that came out recently of reb aaron kotler, and the older books of reb shmuel rozovski of ponovitch, and rav nachum of the mir [rav nachum parzovitch] and isar meltzar the father in law of rav shach and reb aaron. i was not even aware of these books until i found them in a nearby litvak beit midrash.
