The text uses the analogy of a 'parrot tied to a tube.' What does this metaphor represent in the context of the human soul and liberation?

In Chapter 17, the metaphor of a 'parrot tied to a tube' is used to explain the human condition. The text suggests you should advise yourself that you are inherently the "pure Brahman," but you have become bound by the physical body and its associated ego. Like the parrot, the soul is confined by this attachment, which arises from the delusion of Maya and infatuation, causing you to forget your true, free nature. The path to liberation, therefore, is to recognize this bondage, "release the feet that are held tight," and metaphorically fly high in the sky, transcending the illusion of 'I and mine' to reclaim your true form.
