Tehillim, 20th of the month, recite from chapter 97 to chapter 103 inclusive.
Tanya, on this day we continue chapter 42 which we began the previous day. The daily shiur is from the word "vechol zeh", on page 118, until the end of the paragraph on that same page, "kemo shekasuv sham".
The daily teaching is from a sicha that the Rebbe Rayatz related at a Pesach meal in the year 5698, in which he related a custom associated with the holiday of Pesach. And this is the story: "Once, the holy Rav Chaim Avraham, son of the Alter Rebbe, went in to the Mitteler Rebbe" - who was his brother - "on the holiday of Pesach". And what did he go in for? "To say 'Gut Yom Tov'", to wish him a happy holiday.
In that same sicha, the Rebbe Rayatz notes that in Lubavitch they were especially careful and made a point of honoring relatives by saying "Gut Yom Tov", and they would go to all their relatives during the holiday to wish everyone "Gut Yom Tov". The Tzemach Tzedek himself acted this way as well, going around to everyone. And the Rebbe Rayatz relates that before his passing, the Tzemach Tzedek reached an advanced age, and people would come to him; and if a specific person did not arrive, he would ask why he did not come - showing to what extent they were particular about this matter of wishing "Gut Yom Tov" to one another on the holiday.
And here, Rav Chaim Avraham went in to his brother, the Mitteler Rebbe, to wish him a "Gut Yom Tov", and on that occasion he related that the Alter Rebbe said in the name of his father: "And he related then - Rav Chaim Avraham - that the Alter Rebbe said: On Pesach, one does not offer food and drink to another". Meaning, since on Pesach there are various hiddurim, and some are particular about certain hiddurim while others are particular about different ones, there is no need to make things difficult for another person because of the hiddurim of Pesach.
And the emphasis is in both directions: both in that one should not urge him, "Come eat," when perhaps he does not share your hiddurim; and conversely, if he does not want to eat - one should not take offense that he does not taste anything. One should be relaxed in this area of eating and drinking. "But to take on one's own initiative - is permissible" - meaning, to allow anyone who is interested to take for themselves; one should provide the opportunity to take independently, but not pressure anyone to taste anything on Pesach. It is entirely a matter of self-service.
And there is the famous story with Rabbi Meir Shlomo Yanovsky, the Rebbe's grandfather, who was the Rav of Nikolaev, as is known. At a bris meal - which took place in his home in honor of the bris of his grandson, the Rebbe, in the year 5662 - the chossid Rabbi Asher Grossman was present. He did not want to taste anything from the meal, because he was very particular on Pesach not to eat anywhere, even though it was the home of the Rav, and seemingly "one can rely on the Rav, the Rav of the city"; but he did not want to taste anything.
And the story there is that the Rav of the city, Rabbi Meir Shlomo, told him that in fact he should have taken offense at him for not tasting anything in his home; except that there was a whole story, that since that chossid had saved him - by reciting before him the famous Igeres "Lehaskil Ulehavin" at a time when he was immersed in a hasagah - he said to him: Since you saved me, I am not taking offense at you for not tasting anything in my home on Pesach.
In any case, we see this strictness: one should not make things difficult for anyone. On Pesach, people must be given their space, and everyone should conduct themselves according to their own customs and hiddurim.
