R’ Nosson Meir Wachtfogel zt”l (Leket Reshimos) said: “'רק חזק לבלתי אכל הדם' - Rashi quotes the Sifri in the name of Rav Shimon ben Azai: ‘If regarding blood, which is easy to watch out for since a person has no desire for it, [the Torah] needed to strengthen you with its admonition, how much more so [must one strengthen oneself] for all other mitzvos.’ The message here is that one needs strength even to do easy mitzvos. One needs to be passionate and strong even about these ‘easy’ mitzvos lest one’s lack of passion lead him to sin.”

“Remember that the most valuable antiques are dear old friends.”
