An article in Ynet Judaism (in Hebrew) addresses the resentrecent controversy regarding the prayer of Women of the Wall at the western wall. And claims the following claims:
אף אחד גם לא הקריא להן את הגמרא שמספרת על ברוריה אשת רבי מאיר, שהייתה מניחה תפילין ומתעטפת בטלית, וגם לא את זו שמספרת על מיכל בת שאול שהניחה תפילין ולא מיחו בידה, ובטח שלא את פסק ההלכה של הרמ"א שמחייב אותן בברכה על כך.
In short, it claims that the Gemara depicts "Bruria wife of rabbi Meir" and "Michal, daughter of Saul" putting on tefilin and talit, and nobody stopping them. And also, that the Rema said that they are obliged to bless the act (לברך), and thus implying that this is allowed (and maybe even encouraged).
What is the Gemara's and orthodox adjudicators' view on the issue?
I know that this is an English site, but please, when you put references to books and scriptures, put them in Hebrew as well, it makes the job of understanding what is written and checking it by myself much easier.
