What is the significance of the belt tied around Lord Dattatreya's waist?

[Smt. Priyanka asked: Padanamaskaram Swami, Can You please explain the significance of the grass belt tied around Lord Dattatreya's waist? At Your divine lotus feet, Priyanka]

Swami replied:- It is tied just as the belt that is tied around the pants to avoid the slip down of the pants. Don’t be crazy to find internal meaning for everything. The internal meaning here is only prevention of slip of the cloth tied around the waist.
