易經可以自學嗎？自學順序怎麼排

作者：Wei Chun Chuang・2026-10-15

很多人想讀《易經》，卻擔心沒有老師帶會看不懂。其實易經的結構非常規律，只要順序排對，自學完全可行。這篇整理一條適合初學者的自學路線，以及常見的卡關點。

易經真的可以自學嗎？

可以。易經由固定的元件組成：陰陽兩種爻、八個三畫卦、六十四個六畫卦，每卦有卦辭與六條爻辭。這些都是可以一步步學會的知識，不需要特殊天分。自學最大的困難不是內容太深，而是順序錯亂，例如一開始就從艱澀的爻辭讀起，很快就會放棄。

第一步：先學哪些基本概念？

先分清陽爻「⚊」與陰爻「⚋」，再記住八卦的符號與象徵：乾天、坤地、震雷、巽風、坎水、離火、艮山、兌澤。可以用傳統口訣幫助記憶，例如「乾三連、坤六斷」。這一步通常幾天就能完成，卻是之後所有內容的基礎。

第二步：六十四卦要怎麼記？

不要硬背。先練習把每一卦拆成上卦與下卦，例如上坎下離是既濟、上離下坎是未濟。接著認識卦序：通行本分上經三十卦、下經三十四卦，從乾、坤開始，到既濟、未濟結束。熟悉八卦之後，六十四卦就只是八卦的組合。

第三步：卦辭和爻辭怎麼讀？

一次只讀一卦。先讀卦辭，掌握全卦大意；再由初爻往上讀到上爻，觀察六個位置的變化。記得陽爻稱「九」、陰爻稱「六」，「九二」就是第二爻為陽爻。讀不懂的字可以先跳過，把注意力放在整卦的處境與發展上。

第四步：什麼時候讀〈易傳〉？

熟悉經文之後，再參看傳文。〈彖傳〉解釋卦辭，〈象傳〉用卦象說明意義，〈文言傳〉專講乾坤兩卦，〈繫辭傳〉則談易經的整體思想。它們能幫你理解經文，但份量不小，建議放在經文之後。

自學要選哪本書？

手邊準備一本有原文、注釋與白話翻譯的版本即可。傳統上常被參考的注本包括王弼注、程頤《伊川易傳》與朱熹《周易本義》，不同注本的觀點不盡相同，初學時選一本讀到底，比同時翻很多本更有效。

自學最常見的卡關點是什麼？

照這個順序，大約兩三個月就能把六十四卦完整走過一輪，之後每讀一次都會有新的體會。

常見問題

自學易經大概要多久？
因人而異。如果每天讀一卦，約兩個多月可以把六十四卦讀過一輪；之後再搭配傳文與複習，理解會逐步加深。
自學易經需要先學古文嗎？
不需要先專門學古文。選一本有注釋和白話翻譯的版本，邊讀邊查，就能慢慢適應經文的用字。
自學時可以練習起卦嗎？
可以，把起卦當作對照所學、反思自身處境的練習即可。重要的是讀懂卦辭與爻辭，而不是讓結果替你做決定。

想用 App 練習？

如果想讓這條自學路線有人幫你排好，易見是一款從零學易經的 iPhone App：八堂互動入門課（前三堂免費）帶你從陰陽、八卦走到六十四卦，每卦有圖解導讀與小測驗，並有複習排程和錯題本。App 裡的起卦是練習功能，用來反思，不替你做決定。

Can you teach yourself the I Ching? A self-study order that works

作者：Wei Chun Chuang・2026-10-15

Many people want to read the I Ching but worry they can't follow it without a teacher. In fact its structure is very regular, and with the right order self-study works well. Here is a route for beginners and the places where people commonly get stuck.

Can you really teach yourself the I Ching?

Yes. The I Ching is built from fixed parts: two kinds of line, eight three-line trigrams, sixty-four six-line hexagrams, and for each hexagram a judgment and six line statements. All of this can be learned step by step without special talent. The biggest obstacle is not depth but order: start with the obscure line statements and you will likely give up quickly.

Step 1: Which basics come first?

Learn to tell the yang line "⚊" from the yin line "⚋", then memorise the eight trigrams and their images: Qian heaven, Kun earth, Zhen thunder, Xun wind, Kan water, Li fire, Gen mountain, Dui lake. Traditional rhymes help, such as "Qian is three solid lines, Kun is six broken pieces". This takes only a few days but supports everything that follows.

Step 2: How do you remember sixty-four hexagrams?

Don't cram. Practise splitting each hexagram into an upper and a lower trigram: water over fire is After Completion, fire over water is Before Completion. Then get to know the sequence: the received text has thirty hexagrams in the first part and thirty-four in the second, starting with Qian and Kun and ending with After Completion and Before Completion. Once you know the trigrams, the hexagrams are simply their combinations.

Step 3: How do you read the judgments and line statements?

Read one hexagram at a time. Start with the judgment to grasp the overall idea, then read from the first line up to the top line and notice how the six positions develop. Yang lines are called "nine" and yin lines "six", so "nine in the second place" means the second line is yang. Skip words you don't understand at first and focus on the situation and how it unfolds.

Step 4: When should you read the commentaries?

After you are familiar with the classic. The Tuan explains the judgments, the Xiang explains meaning through the images, the Wenyan focuses on Qian and Kun, and the Great Commentary (Xici) discusses the book's overall ideas. They deepen your reading but are substantial, so leave them until after the main text.

Which book should you use?

One edition with the original text, notes and a modern translation is enough. Commentaries traditionally consulted include Wang Bi's, Cheng Yi's Yichuan Commentary and Zhu Xi's Original Meaning of the Zhou Yi. They differ in viewpoint; as a beginner, reading one all the way through works better than flipping between many.

Where do self-learners usually get stuck?

  • Trying to finish fast: the I Ching rewards slow reading, and one hexagram a day is plenty.
  • Casting without reading: casting is fine as practice, but without the judgments and line statements real understanding is hard.
  • No review: names and images stick only if you revisit them a few days later.

Following this order, you can go through all sixty-four hexagrams in about two to three months, and each later reading brings something new.

常見問題

How long does it take to self-study the I Ching?
It varies. At one hexagram a day you can go through all sixty-four in a little over two months; adding the commentaries and review deepens understanding gradually.
Do I need to learn classical Chinese first?
Not as a separate step. Choose an edition with notes and a modern translation and look things up as you read; you will get used to the language over time.
Can I practise casting while self-studying?
Yes, as a way to check what you have learned and reflect on your situation. What matters is understanding the texts, not letting a result make decisions for you.

Practise with an app

If you would like this route laid out for you, YiJian is an iPhone course that teaches the I Ching from zero: eight interactive beginner lessons (the first three free) take you from yin and yang through the trigrams to the sixty-four hexagrams, each with an illustrated guide and quiz, plus spaced review and a mistakes notebook. Casting in the app is a practice feature for reflection; it does not make decisions for you.
