This chapter addresses a significant challenge for individuals striving for spiritual growth: a persistent dullness or insensitivity of the heart. This condition can make it difficult to experience emotional connection during spiritual practices, such as prayer, and to conquer self-centered impulses. The text identifies the root cause of this dullness as an inner arrogance, a sense of self-importance within one's lower nature that obscures the light of the higher self. To combat this, two primary methods are proposed: deep introspection and assertive internal confrontation. The first involves setting aside time for honest self-assessment, reflecting on past thoughts, words, and actions—even seemingly neutral ones—to recognize how often one has been a vessel for unholy influences. This self-awareness should lead to a profound sense of humility and self-abasement. The second method is to actively and internally "rage" against one's negative impulses, calling them out for their inherent falseness and their attempt to deny the omnipresent Divine reality. This internal thunder helps the higher self perceive truth more directly, leading to a deeper sense of connection. The chapter explains that this inner negativity has no true substance and its power is only given so that individuals can actively overcome it, thereby revealing their innate, perfect faith. An example is provided from a historical account where a community's lack of faith was overcome not by external miracle, but by intense divine anger that humbled their rebellious inner forces, allowing their inherent belief to surface.
