Should a soul bring forward a grain offering…Rashi points out that only in relation to grain offerings does the Torah use the word nefesh, soul. The poor could only afford a grain, not animal, offering. Therefore the Torah uses the word soul to teach that even so, it is as if they truly offered themselves. Sfat Emet extends this idea, sometimes a person feels that they can only do a little bit. Instead of looking at how little they’re doing, they should focus on the depth of their intention, as per the first chapter in the Shulhan Aruch: it’s better to bring intention to the little we do, than to do much without any feeling.
