Should a Guru's teachings be kept secret? What does Chapter 18 say about sharing spiritual wisdom?

Chapter 18 strongly refutes the idea that a Guru's teachings should be kept secret, dismissing this notion as an "imaginary and a meaningless fuss." The chapter argues that the Guru is like monsoon rain clouds, showering the "water of self-bliss" for everyone, and questions why this should be kept bottled up. It encourages devotees to partake of this bliss and let others partake as well. To support this, the text cites the example of the sage Budhakaushika, who shared the dream-vision of his Ram Raksha initiation with everyone for their enlightenment, proving that even instructions received in dreams are meant to be shared.
