The Cure for All Problems by Rabbi Benayahu Yissachar Shmueli, Shlit"a
So says the Pele Yoetz, it is the exact same thing: A person who recites the Holy Zohar — it heals him! What do you care if you understand, don't understand, or how it works... it heals! It has spiritual remedy virtues (Segulah)!

Reading and reciting the Book of the Zohar helps cleanse and polish the soul.
And if a person should ask: "What is it worth? I don't understand what I am reading" —
Then the book Pele Yoetz gives a parable regarding this:
For example, a person went to a doctor.
The doctor asks him: "Yes, what seems to be the problem?"
He says he feels weak and isn't feeling well.
The doctor examines him and says: "He has high blood sugar".
"For blood sugar, we need to give him pills to lower his blood sugar levels".
He hands him the pills.
The patient says: "I don't want to take this".
"Why don't you want to? Take them".
He says: "I don't understand how this is going to heal me".
The doctor replies: "What do you care? I studied this illness at university for five years, and after all the research — this is the medicine; it works, it isn't harmful, it will help you, and it will lower your blood sugar so you can live.
Otherwise — may it not be upon you or me — you will face severe troubles: you won't be able to see due to the blood sugar, and, Heaven forbid, you could get necrosis and other severe problems.
Why do you need all these troubles? Heart conditions, strokes...
Why do you need any of this? Take these pills, and you will be healthy".
He says: "No".
"Why not?"
He says: "I don't understand how this will heal me".
"To understand it, you would need to study at a university. But it's a fact — if you take it, you will be healthy.
That's right, if someone wants to understand what it is, they have to study at a university for several years.
What does that matter? The bottom-line result is that it heals".
So says the Pele Yoetz, it is the exact same thing:
A person who recites the Holy Zohar — it heals him!
What do you care if you understand, don't understand, or how it works... it heals!
It has spiritual remedy virtues (Segulah)!
