"The great work must inevitably be obscure, except to the very few, to those who like the author himself are initiated into the mysteries. Communication then is secondary: it is perpetuation which is important. For this only one good reader is necessary"

Henry Miller's quote underscores the mystical nature of profound artistic or literary work, recommending that true understanding of such work is reserved for a select few who share a deep, intrinsic connection or insight comparable to that of the author. In these lines, Miller proposes that extraordinary works are naturally obscure, hinting that their depth and significance are not immediately available or apparent to the general public. Instead, they need a specific level of initiation or extensive understanding, comparable to mysteries or secret understanding.

The expression "to those who like the author himself are started into the secrets" suggests that just people with a particular level of insight or experience can completely value the nuances and underlying messages encapsulated within the work. This concept lines up with the concept that some masterpieces or literature are developed not for mass intake, but rather to resonate on a much deeper level with an audience that shares a particular intellectual or emotional wavelength with the developer.

Further, Miller explains that "communication then is secondary: it is perpetuation which is important". Here, he recommends that the main goal of such work is not always to interact broadly but to withstand over time. The focus is on the extension and conservation of the work's essence and significance, which can be accomplished with the understanding of even a single informed reader. This idea challenges the traditional view that the worth of art or literature lies in its widespread acceptance or appeal. Rather, Miller implies that the true measure of a fantastic work is its ability to maintain its significance and effect, even if it is just genuinely understood by one critical reader.

In summary, Miller's quote highlights the intrinsic power of excellent works to transcend normal understanding, suggesting that their true worth and function depend on their ability to engage and withstand in the hearts and minds of the couple of who can fully appreciating their secret and depth.
