How does the description of love in Chapter 48, where it's called the foundation of devotion, compare with the practical examples of selfless service detailed in Chapter 15?

The provided source material is from Chapter 48 and does not include text from Chapter 15, so a direct comparison of their teachings is not possible. However, Chapter 48 provides a profound description of the supreme importance of love. It states that without love, knowledge is dry and useless, and there can be no satisfaction. This chapter emphasizes that devotion itself dwells where there is love, and that "love does not arise without faith (Bhava)." The text further explains that "love is fully present in the womb of faith," highlighting it as the essential component for crossing the ocean of worldly existence. The greatness of love is described as so immense that everything else is trivial in comparison.
