According to Chapter 18, should the teachings received from a Guru be kept secret? What justification is provided?

Chapter 18 directly addresses the notion that a Guru's instructions should be kept private. The text dismisses this idea as "merely imaginary and a meaningless fuss." It argues strongly for sharing spiritual knowledge, stating that even teachings received in dreams are meant to be told to all for their enlightenment. To support this, Chapter 18 provides the example of the sage Budhakaushika, who famously narrated the dream-vision of his Ram Raksha initiation to everyone. This emphasizes the principle that a Guru's wisdom, like monsoon rain, is meant to be showered universally for the benefit of all.
