The section of Ashreh, which we recite three times each day, contains the famous verse, "Pote'ah Et Yadecha U'masbi'a Le'chol Hai Rason" – "You open Your hands and willfully satiate every living creature" (Tehillim 145:16). This verse is especially significant, and, in fact, it is one of the reasons why we are to recite this chapter of Tehillim three times each day (Berachot 4b). It must therefore be recited with concentration, and it behooves us to properly understand its meaning. While the verse's meaning is generally straightforward, the final word – "Rason" – requires explanation. This word means "will," that which a person wishes for. What exactly did King David mean when he said that Hashem satiates all living beings "Rason"? One explanation is that Hashem does not just give us a livelihood – but He does so willfully, lovingly. Just as a parent loves giving to his or her children, and wants to give them as much as possible, Hashem similarly loves us and wants very much to give us a livelihood. It is his pleasure, so-to-speak, to sustain us. Others explain "Rason" as referring to our will, the will of the beneficiaries of Hashem's kindness. He fills our needs and grants us what we wish for. There is also another possible interpretation of the word "Rason" in this verse. Very often, financial success results from a person's likeability, his finding favor in other people's eyes. He earns other people's respect and fondness, and it is because of this that they buy his product or solicit his services. It is not always the product itself which attracts buyers; sometimes it's the seller's character and demeanor. The phrase "U'masbi'a Le'chol Hai Rason" thus might refer to G-d's providing a livelihood by granting a person "Rason" – a certain charm and likeability. Hashem often helps a person succeed by giving him this quality whereby he attracts customers and his products or services are eagerly sought after. The scholars of Kabbalah have unearthed numerous additional layers of interpretations underlying this verse. The Kaf Ha'haim (Rav Yaakob Haim Sofer, Baghdad-Jerusalem, 1870-1939) writes that the vast majority of people should not try to have deep kabbalistic intentions while praying, and should instead ensure to concentrate on the plain, straightforward meaning of the words. Seeking to pray with these deep intentions could lead one to overlook the plain meaning, and the Kaf Ha'haim warns that this could be harmful to the person's Tefila. Nevertheless, there are two relatively straightforward kabbalistic allusions in this verse which are worthwhile for even us to learn and have in mind while reciting it. The first letters of the words "Pote'ah Et Yadecha" – Peh, Alef, Yod – spell a Name of Hashem that is associated with His providing us with Parnasa. Another Name is formed by the final letters of these words – Het, Tav, Chaf. It is recommended, when possible, to have these Names in mind while reciting this verse in the Tefila. If one recites this verse in Ashreh and then realizes that he recited it without Kavana (concentration), then he must repeat it. This is the ruling of the Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909). If the person realized his mistake before he completed Ashreh, then he simply returns to the verse of "Pote'ah Et Yadecha" and continues from there. If he did not realize his mistake until he began the next chapter of Tehillim ("Hallelu-ya Haleli Nafshi"), then he should complete that chapter and then recite "Pote'ah Et Yadecha…" before beginning the following chapter ("Hallelu-ya Ki Tob Zamra"). Meaning, the verse should be inserted in between the subsequent chapters, and not in the middle of a chapter. If a person realized his mistake only later, after Pesukeh De'zimra, then he should ensure to have Kavana when reciting this verse in Ashreh before U'ba Le'sion. And if he failed to have Kavana also at that point, then he should try again while reciting Ashreh at Minha. Some Poskim maintained that one who did not recite this verse with Kavana and realized his mistake only later should repeat it after the Amida, but Hacham Ovadia Yosef ruled that it suffices to ensure to recite it with Kavana in Ashreh before U'ba Le'sion. The Ben Ish Hai and the Hesed La'alafim (Rav Eliezer Papo, 1785-1828) write that when one needs to repeat this verse, he should begin two verses earlier, from "Somech Hashem Le'chol Ha'nofelim." From the Shulhan Aruch and other Poskim, however, it appears that it suffices to recite just "Pote'ah Et Yadecha…" This is the view of Hacham Ovadia Yosef, in Yalkut Yosef. Nevertheless, if time allows, it is recommended to begin from "Somech Hashem Le'chol Ha'nofelim." Some noted the distinction drawn by Halacha between one who recites "Pote'ah Et Yadecha" without Kavana, and one who recites the first blessing of the Amida without Kavana. While one of course must endeavor to concentrate throughout the entire Amida, one must minimally have Kavana while reciting the first Beracha. Nevertheless, the Halacha is that if one did not have Kavana during the first blessing, he does not repeat the Amida, because of the likelihood that he will not concentrate the second time, either. When it comes to "Pote'ah Et Yadecha," however, as we have discussed, one who recited this verse without Kavana is required to repeat it. Two explanations are given for this distinction. First, quite simply, it is far easier to concentrate while reciting a single verse, and so there is little reason to think that one who did not have Kavana while reciting this verse during Ashreh will not have Kavana when he repeats it. Additionally, Halacha is always more careful when it comes to the recitation of Berachot, given the prohibition against reciting a Beracha in vain. Therefore, a person who did not have Kavana during the first Beracha of the Amida is told not to repeat the Amida due to the concern that he will not concentrate the second time, and the blessings of the Amida will then have been recited in vain. When reciting a verse from Tehillim, however, there is no such concern, and thus the person should repeat the verse despite the possibility that he will not concentrate. It is customary to open one's hands when reciting this verse, which speaks of Hashem opening His hands to give us our livelihood. This is done to symbolize our preparedness to receive the blessing that G-d bestows. Of course, we do not need to actually open our hands to receive the Beracha, but we nevertheless perform this action as a visual expression of our desire to receive Hashem's blessings. The Ben Ish Hai writes that one should open his hands horizontally, side to side, without lifting them up in the air. Some stand for the recitation of "Pote'ah Et Yadecha," but this is not our practice. Summary: One must have Kavana (concentration) when reciting the verse "Pote'ah Et Yadecha…" in Ashreh during the prayer service. If one realized during Ashreh that he had recited this verse without Kavana, then he must go back to recite it with Kavana, and then proceed from there. If he remembers after Ashreh, then he should add this verse in between chapters of Pesukeh De'zimra. According to some opinions, if the person did not realize his mistake until after Pesukeh De'zimra, then he should repeat the verse after the Amida. Others maintain that he should just ensure to have Kavana during Ashreh before U'ba Le'sion. If one needs to repeat this verse, it is preferable to begin two verses earlier, from "Somech Hashem Le'chol Ha'nofelim." It is customary to open one's hands while reciting "Pote'ah Et Yadecha." They should be opened only horizontally, side to side, and not lifted in the air.
