I heard a mind-blowing idea a couple of years back in the name of the Chasam Sofer, and I would really love to know the source....
It says in Vayikra 23:15 -
וּסְפַרְתֶּ֤ם לָכֶם֙ מִמָּחֳרַ֣ת הַשַּׁבָּ֔ת מִיּוֹם֙ הֲבִ֣יאֲכֶ֔ם אֶת־עֹ֖מֶר הַתְּנוּפָ֑ה שֶׁ֥בַע שַׁבָּת֖וֹת תְּמִימֹ֥ת תִּהְיֶֽינָה׃
And from the day on which you bring the sheaf of elevation offering—the day after the sabbath—you shall count off seven weeks - They must be complete:
Whilst these seven complete weeks are understood halachically that one needs to count the days consecutively without dropping a day (refer to Sefer HaChinuch 306:5 and Sefer HaMitzvos 162) they can also be seen as a qualitative measure, namely an auspicious time to work on oneself - a time for self improvement and an 'aliyah' (elevation) in ruchniyos (spiritual matters). We know that the Jewish people at the time of leaving Mitzrayim (Egypt) were on the 49th level of tumah (impurity) and with each subsequent day, ascended till they were on the requisite level of holiness to receive the Torah (e.g. see Kedushas Levi). Thus with each day of sefirah, we are gifted the opportunity to improve ourselves and grow closer to Hakadosh Boruch Hu.
Now here's the Chasam Sofer....
The Chasam Sofer wrote (somehere?!!) that a person can, during this 49 day period, achieve great heights, and on each individual day of Sefirah, can rectify that which would normally require two years of toil. As a result, 49 days of Sefirah (when used productively) can equate to 98 years worth of aliyah in ruchniyus!!!
