What is the stance in Chapter 18 on sharing a Guru's teachings with others? Should they be kept secret?

Chapter 18 directly addresses the idea that a Guru's instructions should be kept secret, dismissing this notion as 'merely imaginary and a meaningless fuss.' The chapter argues that teachings, even those received in dreams, should be shared with all for their collective enlightenment. To support this, it provides the example of the sage Budhakaushika, who narrated the dream-vision of his Ram Raksha initiation to everyone. The text concludes with a metaphor comparing the Guru to monsoon rain clouds that shower the 'water of self-bliss,' reinforcing that spiritual wisdom from the Guru is meant to be shared widely.
