Sefirat HaOmer, the forty-nine-day counting from Pesach to Shavuos, is one of the most spiritually structured periods in the Jewish calendar, with each of the forty-nine days corresponding to a specific combination of the seven lower Sephirot in the Lurianic Kabbalistic system and carrying its own distinct character within the broader arc from liberation to revelation. At Eichlers, we carry Sefiras HaOmer seforim spanning practical halacha compilations on the Omer, Lag BaOmer, and Pesach Sheini, Kabbalistic siddur editions for the Omer period, and Chassidic learning resources on the meaning of counting toward Matan Torah.
Mishnas Hamoadim on Sefiras HaOmer, Pesach Sheini, and Lag BaOmer provides a comprehensive halachic and thematic resource for the full Omer period in a single volume, covering the halachos of the counting itself, the special status and customs of Pesach Sheini on the fourteenth of Iyar, and the celebration and halachic considerations of Lag BaOmer as the yahrtzeit of Rabbi Shimon bar Yochai. This type of comprehensive treatment of the full Omer season is particularly valuable for a maggid shiur or serious learner who wants to address all three significant occasions of this period without maintaining separate resources for each one.
Doresh Tov on Sefiras HaOmer and Lag BaOmer brings the analytical drush approach to the Omer period, engaging with the themes of spiritual refinement, the mourning customs of Sefira, the significance of Lag BaOmer within the Omer count, and the specific character of these weeks as a period of character development and preparation for Matan Torah. This work provides the kind of structured Torah content on the Omer that a learner who wants more than a practical halacha guide but is not yet working through the full Kabbalistic system of Sephirot refinement will find most accessible and immediately applicable to daily Omer practice.
Siddur Rechovos HaNahar for Sefiras HaOmer provides the daily Omer counting text with the Kabbalistic kavanot of the Rashash tradition, organizing the specific intentions corresponding to each day's unique combination of Sephirot into a format usable during the actual nightly counting. This siddur is produced for the Sephardic Kabbalistic tradition centered around the Yeshiva HaMekubalim Nahar Shalom and serves the serious student of Lurianic Kabbalah who wants to perform the Omer counting at the highest available level of mystical intentionality rather than simply reciting the standard text.
Gems from the Nesivos Shalom covering Chag HaPesach and Sefiras HaOmer brings the teachings of the Slonimer Rebbe, Rav Shalom Noach Berezovsky, to the Omer period in an accessible English format drawn from his monumental Nesivos Shalom series. The Slonimer Rebbe's approach to Sefiras HaOmer emphasizes the character refinement and spiritual preparation for Matan Torah that the Omer period demands at a deeply personal and practical level, making this work one of the most directly applicable English-language resources for using the Omer period as genuine avodah rather than simply a countdown to Shavuos.
Each of the forty-nine days of Sefirat HaOmer corresponds to a specific combination of the seven lower Sephirot, Chesed, Gevura, Tiferes, Netzach, Hod, Yesod, and Malchus, with the seven weeks structured so that each week addresses one primary Sephirah and each day within the week addresses a secondary Sephirah within it. Day one is Chesed shebeChesed, pure lovingkindness within lovingkindness. Day seven is Malchus shebeChesed, sovereignty within lovingkindness. Day forty-nine is Malchus shebeMalchus, the culmination of the entire refinement process. The Siddur Rechovos HaNahar makes this structure practical during daily counting, while the Doresh Tov and Mishnas Hamoadim volumes provide the explanatory framework for understanding what the counting is actually accomplishing spiritually.
Lag BaOmer, the thirty-third day of the Omer count, is the yahrtzeit of Rabbi Shimon bar Yochai, the author of the Zohar, and is celebrated across the Jewish world as a day of festivity during the otherwise semi-mourning period of Sefira. Works like Mishnas Hamoadim and Doresh Tov that address Lag BaOmer specifically within their Omer content provide both the halachic framework for understanding why Lag BaOmer marks a break in the Sefira mourning customs and the Kabbalistic significance of this day as a celebration of the revelation of the Zohar's wisdom through Rabbi Shimon's life and final day.

Sefiras HaOmer is the Torah commandment to count forty-nine days from the second night of Pesach through the eve of Shavuos, commemorating the period between the Exodus from Egypt and the giving of the Torah at Sinai. The counting is performed each night after nightfall with a specific bracha and is recorded in Vayikra and Devarim.
Lag BaOmer, the thirty-third day of the Omer, is the yahrtzeit of Rabbi Shimon bar Yochai, on which day he revealed the deepest secrets of the Torah and rejoiced rather than mourned his departure from this world. It is celebrated with bonfires, outings, music, and festivity as a break within the semi-mourning period of Sefira.
Pesach Sheini, the fourteenth of Iyar, is a minor holiday on which individuals who were ritually impure or far away on Pesach could bring the Pesach offering one month later. It carries the lesson that there is always a second chance in avodas Hashem, and it falls within the Sefira period between Pesach and Shavuos.
