Beautiful Book Filled With Timeless Wisdom And Poetic Imagery
Format: Hardcover
This book just entered the public domain here in the United States and I heard good things about it so I thought I order a copy to celebrate Public Domain Day and introduce myself to this classic work of literature. This is a nice, sturdy hardcover edition from Penguin Classics with blue gilding on the pages and a sweet forward by Rupi Kaur who herself was inspired by the book growing up.
With the first page, I was hooked and read the whole way through. The language is so elegant and rhythmic, and the lessons being taught are quite profound, for example the section on "Crime and Punishment" and how it speaks about citizens viewing criminals as "strangers" when they themselves have the same propensity to committing similar acts really stood out to me upon my first reading.
Even though it's a very short book (about 100 pages long), it is so dense with imagery that it could take multiple re-readings in order to grasp every detail and inner truth being written. I plan to revisit this book every now and again in order to do so and it would serve as a nice companion for my life's journey. I highly recommend this to everyone.

beautiful!
Format: Kindle
The Prophet is a loftily written expose of the governing universal laws of love, rhythm, correspondence, cause and effect, dualism and polarity. I absolutely loved it and would not have understood it should it have presented itself to me earlier than this present moment. Deeply grateful for the lessons it beholds.

CLASSIC WORKS BUT SIZE & FORMAT ALMOST TOO SMALL TO READ
Format: Hardcover
This work is classic literature. But sadly, the product presentation doesn't make it clear how small the edition is -- 5x7 inches -- and how terribly small the font size is -- like 14 pt. It's really not readable -- but more a way to possess a treasured piece.

🏜️ Arrakis. Dune. Desert Planet.
Format: Paperback, Format: Paperback
Earlier this year, I decided to actively stop doom scrolling. With the help of Opal to limit my access to social media on my phone, I had a ton of time to kill. I didn't want to go back to playing video games, I have probably played enough video games for two lifetimes, and I could only spend so much time job hunting, so I decided to give reading a real shot.
Truth is, I never enjoyed reading as a kid. It always felt like homework, like something forced, and that took all the fun out of it.
So why did I pick Dune? I really enjoyed the movies by Denis Villeneuve, and something about the book pulled me in. At that point, I could not tell if I chose Dune or if Dune chose me.
📖 Now onto the actual review. 🚨 Spoiler Alert 🚨
“The mystery of Dune is not a problem to solve, but a reality to experience.”
Dune feels less like a book and more like entering a world that already exists. Published in 1965 by Chilton, a company better known for auto repair manuals, it is packed with politics, philosophy, religion, ecology, prophecy, drugs, hallucinogenics, and deep world building.
Following Paul Atreides (protagonist) from royal heir to outcast to leader of the Fremen to emperor felt like going through a transformation alongside him. I found myself learning about resilience, how to navigate a future you can see coming but cannot avoid, and what it really means to lead. Each chapter gave me something to think about.
Even more, Dune feels very relevant today given our current political climate. Power, manipulation, religion, and control over resources are all central themes, and they hit differently when you look at the world around you.
💡 Pro tip for reading Dune
Frank Herbert does not hold your hand. He drops you into a world filled with esoteric technology, unfamiliar terminology, and a culture with its own rules. It can feel overwhelming at first, but do not get discouraged if you do not understand everything right away. Let the world unfold as you go.
I ended up reading the first three books in the series, Dune, Dune Messiah, and Children of Dune, and then went back to re-read Dune. This review is based on that second read, and it is amazing how much more you pick up the second time through.
What also helped was reading the graphic novels alongside the book. They do not include every detail, but they stay faithful to the story and help bring the world to life visually.
Also, if you have not watched the recent movies directed by Denis Villeneuve, they are worth checking out. I saw them before reading, and they helped me better understand the characters and major plot points.

Dune
A book review by Nathan Poulson
Written by Frank Herbert in 1959, “Dune” is an epic adventure of political betrayal, ecological brinkmanship, and messianic deliverance. It won science fiction’s highest awards—the Hugo and the Nebula—and went on to sell more than twelve million copies during Herbert’s lifetime. The mantel piece of sci-fi, Star Wars, owes many of its’ widely popular ideas to Dune. To this day, it is still acclaimed by readers and critics alike as a “science-fiction masterpiece”. I highly recommend it to all readers, as I believe it will put a new perspective on things, deepen your understanding, and excite you to the edge of your seat.
Dune follows the 15 year old boy Paul Atriedies and his mother, Jessica Atriedies in the very distant future. He is an only child of the duke of the Royal house of Atriedies. The house is given the stewardship over the desert planet of Arrakis or “Dune”, which controls the most valuable resource in the universe, the spice. On the planet where water is more valuable than gold, desert sand worms that are bigger than spaceships, life is lived to the extreme. With the spice comes a longer life span, increased perception, and in some cases prediction of the future, but at the cost of being highly addictive. The Harkonens, a noble house that previously owned the planet is intent on revenge and recapturing the spice. The spacing guild, which relies on the spice for navigating their spacecraft, is also intent on preventing anyone restricting or destroying their monopoly on space travel. Paul finds himself thrown into the mystery of Dune and its fierce natives, the Fremen. They think he is the savior their prophecy speaks of - is he destined to be the great preserver of their world or a false prophet to be purged? With multiple factions fighting, deceiving, and pulling strings, you never know quite what to expect in this awesome futuristic battleground.
One side I really like about Dune is that it is not just a distant sci-fi to be enjoyed, but a book to learn and understand from. I really enjoy the themes Herbert establishes in the plot; one of them including the danger of entrusting too much power to a super being. Although his themes might be very serious and almost depressing, I admire that he has the courage to end the story based in reality, instead of a unrealistic Hollywood ending with no depth.
Although the plot was very engaging, at some times the writing style really dragged things down. This can be a real turn off for even patient readers as Frank ambles around in unimportant details describing made up words and the very boring thought process of the characters. This is the one thing that made this otherwise a perfect book. Even though I thought the plot was almost pulling me down, somehow I still enjoyed it through the few sparks of almost perfect harmony when the style actually worked for the story.
What makes Dune so special is the pure atmosphere. You can really tell that Frank put in a lot of effort into his fictional world and society. Even though the story is set in another universe, the planets, the characters, and the motives seem very real. He had the worlds built before he set the plot on them; you can see he studied Greek and Near East history extensively to make this book really come to life.
Most books have characters that you can easily relate to. With Dune, it is a little bit harder to do that. In it, you have a story that instead of a personal account, it is more like a “retelling” and it is sometimes a little harder to relate to the feelings and values of the characters. My favorite character Paul is the most distant character for most of the book. Most of this isolation comes from the fact that people look to him as an idol, even though he still has human flaws. Throughout the book Paul is the character with the most burdens, and in constant pressure that he doesn’t measure up to other’s expectation of him. “They think they have a God, but I am only a man”. In reality he is a character we can all reflect from, he just has some layers in his personality that you have to peel away to really get to the core.
This book is near from perfect, but it still hits home. Frank Herbert has done a difficult thing that combines ancient myths and stories with laser guns and mind control. He was the first one to do it, and the last to do it so well. Even without its deeper meanings, this is still a great read to just casually absorb. I cannot explain to you how amazing this book really is; so experience it yourself and pick up a copy, you will be surprised to what it has to offer.
