[57a middle] Rava: Unlike in the case of a Kohen’s death, when a Kohen becomes maimed (and does not cohabit with his wife thereafter), his wife is still permitted to eat Terumah (offerings for Kohanim). Once the wife has been eating Terumah already (and is still married in a relationship) we dot not revoke her rights. But, if she never even started eating yet, it might be much more difficult for the Rabbis to allow her to partake in Terumah in the first place.
R’ Rosner quoting Chazal: It is like a heavy load on the back of a donkey that starts to fall and only needs just two people to rebalance it. However, once it completely falls to the ground at least five men would need to work together to pick it back up.
D-E-ep Thoughts: We should always try to take care of actions and our character traits before they develop into much more lengthy and difficult projects. By trying to learn more Torah everyday and establishing our closer connections to Hashem, we are not only making the most of our current moments, but also establishing much fortitude for the future. We should never let a day go by where we just do the same routine as the day before. Strive to reach new lofty levels and when G-d sees us trucking along the path, He will help us move even further along even faster.
