אלו דברים שאדם אוכל פרותיהם בעולם הזה והקרן קימת לו לעולם הבא, ואלו הן: כיבוד אב ואם וגמילות חסדים והשכמת בית המדרש שחרית וערבית והכנסת אורחים ובקור חולים והכנסת כלה ולווית המת ועיון תפילה והבאת שלום בין אדם לחברו ובין איש לאשתו ותלמוד תורה כנגד כולם.
These are the precepts whose fruits a person enjoys in This World but whose principal remains intact for him in the World to Come:
They are: honoring one's father and mother, acts of kindness, early attendance at the house of study morning and evening, hospitality to guests, visiting the sick, providing for a bride, escorting the dead, absorption in prayer, bringing peace between man and his fellow, and the study of Torah is equivalent to them all.
Torah learning would be more beneficial than saying Tehillim during the spare time on Rosh Hashanah. Rav Y. B. Soloveitchik states that once, his father, Rav Moshe Soloveitchik, zt”l, saw him saying Tehillim on Rosh Hashanah and took the siddur from him, replacing it with Maseches Rosh Hashanah. He then said to his son, “My father (Rav Chaim) would learn the laws of shofar, etc., because that is what the day represents (and on Yom Kippur he would learn the rituals of that day) because that is where Hashem’s world is today.”
