Why does the author claim that worldly relationships, like family, are not helpful for achieving one's spiritual goals?

According to the insights in Chapter 45, worldly relationships are not reliable for spiritual attainment because they are rooted in material concerns. The text suggests that family members act from their own limited perspectives: a mother and father will show affection, a son will be focused on the wealth he can inherit, and a wife will mourn for her own potential widowhood. The author posits that none of these individuals can serve as a true companion on the spiritual path. This is because their attachments are to the transient world. The text concludes that for the ultimate spiritual goal, one must look beyond these relationships and ultimately rely on one's own self and the Guru.
