How does the text describe the reliability of worldly relationships when it comes to achieving one's spiritual goals?

Chapter 45 presents a critical view of worldly relationships in the context of spiritual attainment. It argues that while family members like parents, sons, or a wife may show affection, their support is ultimately transient and unreliable for achieving the spiritual goal. The text bluntly states that those who do not help in worldly life cannot be expected to help in the spiritual goal. It paints a picture where a son is focused on his inheritance and a wife on her own potential widowhood, concluding that 'no one is a companion in the spiritual goal.' Ultimately, as Chapter 45 suggests, upon final reflection, only one's own self remains, emphasizing the need for self-reliance on the spiritual path.
