What is the perspective offered in Chapter 18 regarding the sharing of a Guru's teachings?

Chapter 18 directly refutes the idea that a Guru's instructions should be kept secret from others, calling such a notion an "imaginary and a meaningless fuss." The text strongly advocates for sharing spiritual wisdom, stating that not only direct instructions but even teachings received in dreams should be shared for the enlightenment of all. To support this view, Chapter 18 cites the example of the sage Budhakaushika, who narrated his dream-vision of the Ram Raksha initiation to everyone. The Guru is likened to monsoon clouds that shower the water of self-bliss on everyone without reservation.
