“Bind [isru] with dense-leaved branches [ba’avotim] on the Festival until the horns of the altar” (Psalms 118:27), which alludes both to the binding of the lulav and to the myrtle branch, referred to in the Torah as the branch of a dense-leaved tree [anaf etz avot]. Rabbi Yirmeya said in the name of Rabbi Shimon ben Yoḥai, and Rabbi Yoḥanan said in the name of Rabbi Shimon HaMeḥozi, who said in the name of Rabbi Yoḥanan HaMakkoti: With regard to anyone who establishes an addition [issur] to the Festival on the day after the Festival by eating and drinking, the verse ascribes him credit as though he built an altar and sacrificed an offering upon it, as it is stated: “Add [isru] to the Festival with fattened animals [ba’avotim] until the horns of the altar.

(1) ...On Mondays and Thursdays during the morning service and on Shabbat during the afternoon service, three people read from the Torah; one may neither decrease the number of readers nor add to them. And one does not conclude with a reading from the Prophets [haftara] on these occasions. Both the one who begins the reading and the one who concludes the reading from the Torah recite a blessing; one recites before the beginning of the reading and one recites after its conclusion, but the middle reader does not recite a blessing.

(2)On the days of the New Moon and on the intermediate days of a Festival, four people read from the Torah; one may neither decrease the number of readers nor add to them. And one does not conclude with a reading from the Prophets. Both the one who begins the reading and the one who concludes the reading from the Torah recite a blessing. The first reader recites a blessing before the beginning of the reading, and the last reader recites a blessing after its conclusion, but the middle readers do not recite a blessing. The mishna formulates a general principle with regard to the number of people who read from the Torah on different occasions. This is the principle: Any day on which there is an additional offering sacrificed in the Temple and that is not a Festival, i.e., the New Moon and the intermediate days of a Festival, four people read from the Torah; on a Festival, five people read; on Yom Kippur, six people read; and on Shabbat, seven people read. One may not decrease the number of readers, but one may add to them. And on these days one concludes with a reading from the Prophets. Both the one who begins the reading and the one who concludes the reading from the Torah recite a blessing; one recites before the beginning of the reading and one recites after its conclusion, but the middle readers do not recite a blessing.

(1) It is a Mitzvah to increase in meals of Rosh Chodesh.

Behold, for the man sanctified with the holiness of his Creator, even his physical deeds become actual matters of holiness. A sign of this is in the eating of temple offerings, which is itself a positive commandment, and our sages of blessed memory said: "the priests eat and the owners obtain atonement" (Pesachim 59b).

(1)That all of one's intentions be for the sake of Heaven. And there is one paragraph in it.
If it is impossible for him to study without sleeping in the afternoon, he should sleep. Rema: And when he wakes from his sleep, he does not need to recite the blessing, "My Lord, the soul..." (Beit Yosef). And some say that he should read, "May the pleasantness..." before he sleeps (Kol Bo). [And this is] so long as he does not make it long; as it is forbidden to sleep during the day more than the sleep of a horse, which is sixty breaths. And even in this little, his intent should not be for the pleasure of his body, but rather to strengthen his body for the service of God, may He be blessed. And likewise with anything that is pleasant for him in this world, his intent should not be for his pleasure, but rather for the service of the Creator, may He be blessed; as it is written (Proverbs 3:6), "In all of your ways, know Him." And the Sages said, "Let all of your actions be for the sake of Heaven." As even optional things – such as eating, drinking, walking, sitting, getting up, sexual relations and conversation – all of them should be for the service of your Creator or for something that enables serving Him. For even if one was thirsty or hungry – if he ate or drank for his pleasure, it is not praiseworthy. Rather he should intend to eat and drink for his sustenance, to serve his Creator. And likewise even to sit in the council of the righteous, to stand in the place of the saintly and to go in the path of the straight – if he does it for his own pleasure and to fulfill his desire, it is not praiseworthy; only when he does it for the sake of Heaven. And likewise with laying down: There is no need to say that at a time when he is able to be in involved with Torah study or with commandments, he should not entice himself with sleep to enjoy himself. Rather even at a time when he is weary and needs to sleep in order to rest from his weariness – if he does [so] for the pleasure of his body, it is not praiseworthy. Rather he should intend to give sleep to his eyes and rest to his body for the requirements of health, so that his mind not get jumbled during Torah study on account of sleep deprivation. And likewise with sexual relations: Even at the time [prescribed] by the Torah, if he does [it] for the pleasure of his body, it is disgraceful. And even if his intent is in order that he will [produce] children that will serve him and take his place, it is not praiseworthy. Rather he should intend that he will [produce] children for the service of his Creator; or he should intend to fulfill the commandment of the [prescribed] time, like someone who is paying his debt. And likewise with conversation: Even to recount words of wisdom, his intent must be for the service of the Creator or for something that leads to serving Him. The principle of the matter [is that] one is obligated to put his eyes and his heart to his ways and evaluate all of his actions on the scales of his intellect: So when he sees something that will bring him to serving the Creator, may He be blessed, he should do it. But if not, he should not do it. And one who acts like this will be serving his Creator constantly.
