The text says only 'one's own self remains at the end.' What does this imply about relying on others for spiritual progress?

This statement from Chapter 45 underscores the idea that a spiritual seeker must ultimately be self-reliant. The text explains that worldly relations, including parents, sons, and wives, cannot be fully relied upon as companions in the spiritual goal because their affection is tied to worldly concerns like wealth or social status. Therefore, a seeker of liberation should give up hope in others, maintain strong self-confidence, and take personal responsibility for their journey. Upon final reflection, the text concludes that only one's own self remains to achieve the ultimate spiritual aim.
