I've heard some say a Guru's teachings are private. What do the texts say about sharing a Guru's instructions with others?

The idea that a Guru's instructions should be kept secret is directly refuted in Chapter 18. This notion is described as a 'meaningless fuss.' The text encourages the open sharing of the Guru's words, stating that not only direct instructions but even those received in dreams should be told to all for their enlightenment. As proof, it cites the sage Budhakaushika, who narrated his dream-vision of the Ram Raksha initiation to everyone. The Guru is compared to a rain cloud showering self-bliss, and the teaching is that one should partake of this bliss and let others partake too, rather than keeping it 'bottled up.'
