Is spiritual knowledge enough on its own, or does Baba emphasize another quality as being more important for a devotee?

According to the teachings in Chapter 48, spiritual knowledge alone is insufficient and can be barren. The text describes knowledge without love as 'dry' and questions its use to anyone, stating that without love, there can be no real satisfaction. A metaphor is used to clarify this: a devotee's heart is a lamp, where a mind of theism and a state of faith are the lamp-dish. Love is the essential oil needed to light the wick, which then allows the 'flame of knowledge' to manifest. Therefore, love must be uninterrupted, as it is the indispensable quality that gives purpose and life to knowledge.
