Musar for Yoma 144:6

One can also explain these verses in accordance with a statement by our sages (Yuma 72) that there are three crowns, the crown of priesthood acquired by Aaron, the crown of Monarchy acquired by David, and the crown of Torah which was granted (potentially) to everybody. Concerning all this, the Torah first says (plural) והייתם, "you will all be something precious." There is a discussion in Baba Kama 87 about the meaning of the word סגולה. Rav Chisda holds that someone could acquire סגולה by purchasing a Torah scroll. Rabba bar Rav Hunna thinks that ownership of a date-palem constitutes possession of a סגולה; the owner will be able to eat dates from it for an unlimited period of time. What Rabbi Chisda meant was that everybody is at liberty to buy a Torah scroll, hence everybody can acquire the status of being or possessing a סגולה.
