The book HaYom Yom, from Day to Day, daily is a source of deep insights that I find very profound...2 Adar II, 5765 - March 13, 2005...
A B'racha (a blessing) must have a hold in something, [A blessing has no effect in a vacuum] just as rain benefits only the plowed and sown field, and early and later heavy rains benefit the crops of field or vine. But a waste field, unplowed and unsown, will benefit from neither soft rain, nor the early or later heavy rains.
This lesson teaches us that to receive a blessing, one must create a vessel. This is done by performing mitzvot and good deeds, creating a merit to contain / hold / draw in the blessing. (Contain, to receive it, Hold, to keep it, Draw In, at the highest level to actually bring it.)
