Can you provide a list of chants or mantras mentioned in the Chavadi procession that can help with focus and concentration for studying?

The passages from Chapter 37 describe a vibrant and joyous atmosphere during the Chavadi procession, filled with music and chanting. It mentions "the chanting of Sai’s name" and a "single chant of Hari’s name" being sung by the devotees with love. The air was filled with cries of victory for Sai. However, the text does not provide the specific wording of any formal chants or mantras intended for improving focus or for study purposes. The chanting is depicted as an expression of collective devotion and joy during the procession, rather than a prescribed spiritual practice for individual concentration, as seen in Chapter 37.
