What does the story of Kaka Dixit and the goat illustrate about the nature of a true disciple's devotion?

The story of Kaka Dixit demonstrates the absolute surrender required of a true disciple. As Chapter 23 details, despite being from a pure Brahmin family and a practitioner of non-violence, Kaka was ready to kill a goat simply because it was his Guru's command. For him, the greatest sin was breaking the Guru's command, not the act of killing. This incident, as described in the source, shows that a true disciple has no independent thought separate from the Guru's will, leaving all considerations of right, wrong, fame, or sin to the Guru. His mind is solely focused on executing the command without hesitation.
