Could you explain me in the Rashi Mitpalel shel mincha, why does he say "nikra poshea GAM..."
Rashi means to say that the person is already called a Poshe'a for delaying Musaf (as he writes in his next comment). Since he has already delayed Musaf, he should not pray Musaf first and thereby delay Minchah and be called a Poshe'a for delaying Minchah as well . (See our Insights to Berachos 28a, accessible from http://www.dafyomi.co.il/today.htm).
Dear Kollel, Thank you for the response. If I may ask a followup, the maskana of the gemara seems to be to reject Rabban Gamliel, which is to say that students may be accepted into the yeshiva even if they aren't tocho k'varo. Which position do you think is more educationally sound--RG's or the maskana's? And where do most halachic authorities fall out on this issue? Thanks, Lee Buckman
RAV REUVEN MARLOGIOS (in YESOD HA'MISHNAH V'ARICHASAH) explains at length that Raban Gamliel followed the approach of Beis Shamai with regard to minimizing the quantity of students in order to maximize the quality and to teach only those who are "Tocho k'Varo." Accordingly, we follow Beis Hillel l'Halachah, and thus in practice an educator should -- in general -- be open to teaching everyone.
