I'm reminded of this excerpt from the Lotus Sutra:
"The true entity of all phenomena can only be understood and shared between Buddhas [Helmsmen]. This reality consists of the appearance, nature, entity, power, influence, inherent cause, relation, latent effect, manifest effect, and their consistency from beginning to end." [insertion of Helmsmen by Michael Murphy]
I'm also reminded of the interconnected-ness expressed by the modern philosophical use of the chinese character 經 used to express the word sutra in the title of the Lotus Sutra in modern Chinese, namely: Immanent.
Immanence, in philosophy and theology, is a term applied, in contradistinction to “transcendence,” to the fact or condition of being entirely within something (from Latin immanere, “to dwell in, remain”). Its most important use is for the theological conception of God (Mystic Law, etc.) as existing in and throughout the created world, as opposed, for example, to deism, which conceives him as separate from and above the universe. This concept has been expressed in a great variety of forms, including theism and pantheism.
So basically the introduction of each chapter of the Lotus Sutra starts with the phase: This mystic law of the simultaneity of cause and effect is immanent.
Legend says that when the Lotus Sutra was to be translated from Sanskrit to Chinese by Nagarjuna that basically a new version of "philosophical" Chinese was invented. That is why the classical Chinese versions of the character in the title which stood for "Sutra" when viewed by modern Chinese are interpreted in various ways, e.g. teaching, sutra, throughput, warp and weave, etc.; but interestingly all related to interconnected-ness.
Isn't the act of teaching essentially pointing out the interconnection of things?
Though I enjoyed the Hitchhiker TV series as a young man (I’m 66 years old), I never actually read the books. I think I’ll skip ahead and read Dirk as you have recommended. While I enjoy Dirk, you can enjoy the short treatise whose introduction is quoted below with a link to its entirety.
“If you wish to free yourself from the sufferings of birth and death you have endured since time without beginning and to attain without fail unsurpassed enlightenment in this lifetime, you must perceive the mystic truth that is originally inherent in all living beings.” On Attaining Buddhahood in This Lifetime, written by Nichiren Daishonin in the year 1255
