Early in the chapter, there's a prayer asking for calamities instead of happiness. What's the philosophy behind such an unusual request?

The prayer mentioned in Chapter 22 is, "O Lord God, give happiness to others who ask for it; Give me a constant series of sorrows, so I do not forget Your name." The philosophy behind this seemingly paradoxical request is that constant sorrow and difficulty can serve as a powerful tool to keep a devotee focused on God. The idea is that in times of trouble, one is more likely to remember and call upon the divine. By asking for calamities, the devotee seeks to ensure that God's name will be an "eternal ornament" on their neck, implying a state of perpetual remembrance and closeness to God, which they value more than worldly happiness.
