Chapter 18 argues against keeping a Guru's teachings secret. Could you elaborate on the reasoning and evidence provided in the text?

Chapter 18 directly confronts and refutes the notion that a Guru's instructions given to one person should be kept secret from others. The author dismisses this idea as an "imaginary and a meaningless fuss." The chapter posits that all teachings, including not only direct instructions but even those received in dreams, should be shared for the collective enlightenment of all. To substantiate this point, as mentioned in Chapter 18, the text provides the example of the sage Budhakaushika, who shared the dream-vision of the Ram Raksha initiation with everyone. This serves as proof that divine knowledge is meant to be disseminated, not hoarded, for the benefit of humanity.
