Chasidut sobre Demai 2:3
הַמְקַבֵּל עָלָיו לִהְיוֹת חָבֵר, אֵינוֹ מוֹכֵר לְעַם הָאָרֶץ לַח וְיָבֵשׁ, וְאֵינוֹ לוֹקֵחַ מִמֶּנּוּ לַח, וְאֵינוֹ מִתְאָרֵח אֵצֶל עַם הָאָרֶץ, וְלֹא מְאָרְחוֹ אֶצְלוֹ בִּכְסוּתוֹ. רַבִּי יְהוּדָה אוֹמֵר, אַף לֹא יְגַדֵּל בְּהֵמָה דַקָּה, וְלֹא יְהֵא פָרוּץ בִּנְדָרִים וּבִשְׂחוֹק, וְלֹא יְהֵא מִטַּמֵּא לְמֵתִים, וּמְשַׁמֵּשׁ בְּבֵית הַמִּדְרָשׁ. אָמְרוּ לוֹ, לֹא בָאוּ אֵלּוּ לַכְּלָל:
Alguém que assume ser um Chaver [aquele que observa escrupulosamente o dízimo e as leis da pureza] não pode vender a uma pessoa ignorante produtos úmidos ou secos, nem comprar dele produtos úmidos, nem ser convidado de um Am. HaAretz nem o hospeda como hóspede [quando está vestido] com suas [próprias] roupas. O rabino Yehudah diz: "Ele não pode nem criar pequenos animais, nem se descontrolar em relação a votos e entretenimento, nem se contaminar por [contato com] um cadáver e frequentar a casa de estudo". Disseram-lhe: "Estes não estão incluídos no princípio geral".
Hakhsharat HaAvrekhim
But now we have no Temple, no Cohen who has a ritually pure object to give, no continual offering nor even the altar to atone for our sins, and no ashes of the red heifer to purify us from defilement, only cigarette ashes to smear on our heads and let us remember what we had and what we need to yearn for. If we could only do what we need to do to change our bereavement into holy simchah, we would be standing before the Temple in an instant.
The defilement that the Rebbe is hinting at is a spiritual defilement. Not a concrete defilement of ritual impurity, where if I touch a wet apple I have to be aware that I have just defiled the apple, but the defilement of a cold, unfeeling avodah, where I am saying the words of the prayers by not aware what I am saying or to Whom I am praying. But in the interest of accentuating the positive, which we should all strive to do, let us say that a pure avodah is an avodah with a revealed soul. And in order to preserve this pure avodah, the Piasesner Rebbe advises even a Chassid who is not connected to an association to fulfill all of the advice given to the association as every word of advice is a method that facilitates this revelation. In this way, members of a chevraya need not suspect a lone servant of God and cast aspersions on his avodah, or in the context of our discussion, alienate him simply because he is not a part of the group. This advice is a way of fostering unity if not among all Jews, because “you need to learn to walk before you can run,” and as he said a member who is not suitable could harm the interests of the chevraya, but at least among the Chassidim, where there is much work to be done. In truth, such a vow should be said before three Jews, but on this point we will not be overly strict, and it is enough for him to accept the conditions alone before his Master. We will provide you with a text of the vow below.
