I suppose everyone has their favorite chapter of Tehillim, one that speaks to their soul. Which psalm did the rabbis of the Talmud like best?
The answer is probably chapter 145, commonly called Ashrei (although the Sages referred to it as Tehillah LeDavid, after its opening phrase). In fact, the Talmud (Berachot 4b) states that one who recites this psalm three times a day is assured of a place in the World to Come. It is also the centerpiece of pesukei d'zimra, the collection of psalms forming the introductory section of the morning prayer service.
What makes Ashrei so wonderful? The Talmud explains that this chapter has two special characteristics:
Every psalm has something special. What is the significance of these two advantages? Why are they so important?
One explanation is that these two aspects of Ashrei affirm our most basic beliefs.
The two fundamental tenets of Judaism are that
Ashrei affirms both of these tenets. It contains all the letters of the alphabet — the letters with which God created the world. And the verse “You open Your hand and satisfy the wants of every living thing” confirms our belief in Divine providence.
A second explanation connects Ashrei to one’s personal spiritual growth. There are two requirements to attain ethical and spiritual goals:
The verses of Ashrei are organized according to the twenty-two Hebrew letters. These letters are the ‘building blocks’ of the Torah. By praising God with all of these letters, we recognize that closeness to God is attained through the Torah’s enlightenment.
To avoid being distracted by worldly pressures, we need complete trust in God. By stating, “You open Your hand and satisfy the wants of every living thing,” we are proclaiming that God watches over and protects all creatures. This affirmation of faith bolsters our reliance on God’s providence, so that mundane worries will not succeed in distracting us from our true goals.
