According to the text, should a Guru's teachings be kept secret from others? What justification is provided?

Chapter 18 directly addresses the idea that a Guru's instructions should be kept secret, dismissing it as an "imaginary and meaningless fuss." The author argues that not only direct instructions but even those received in dreams should be shared for the enlightenment of all. To support this, the text provides the sage Budhakaushika as proof, who famously narrated the dream-vision of the Ram Raksha initiation to everyone. This emphasizes the universal nature of the Guru's wisdom, which is meant to be shared widely.
