Final answer:
Prince Harweda is freed from the magic prison after he selflessly frees a bird, demonstrating a change from selfishness to an empathetic character, which is a common theme in tales where personal growth leads to overcoming obstacles.
Step-by-step explanation:
In the story, Prince Harweda is freed from the magic prison because he performs an unselfish act by freeing the bird and feeling glad for the bird's freedom rather than for his own benefit. The magic prison, often a literary symbol for personal transformation or test, only releases the prince after he has demonstrated a change in character, moving away from selfishness towards compassion and empathy.
This shift in Harweda's behavior is a common theme in folk and fairy tales where a character must show growth or virtue to overcome an obstacle or to be rewarded. His action of freeing the bird without any selfish desire indicates that he has indeed learned a valuable lesson about selflessness, which is key to his liberation.
