The Output Stars: Siksin and Sanggwan, Explained

Explore the meanings of siksin and sanggwan in Saju astrology. Learn how they influence your life's output and expression.

The Output Stars: Siksin and Sanggwan — Korean Saju

In the intricate world of Saju astrology, siksin (output star) and sanggwan (expression star) play crucial roles in shaping one's life path. Understanding these concepts can provide valuable insights into your daily output and how you present yourself to the world.

Why Saju Works This Way

Saju astrology is KOREAN and SOLAR / 24 solar terms based. The year starts at ipchun (~Feb 4). It is NOT lunar and NOT based on planets — it reads the calendar of stems and branches. The generating cycle in Saju works as follows:

  • Wood generates Fire
  • Fire generates Earth
  • Earth generates Metal
  • Metal generates Water
  • Water generates Wood

Stems: 甲 Gap=Yang Wood, 乙 Eul=Yin Wood, 丙 Byeong=Yang Fire, 丁 Jeong=Yin Fire, 戊 Mu=Yang Earth, 己 Gi=Yin Earth, 庚 Gyeong=Yang Metal, 辛 Sin=Yin Metal, 壬 Im=Yang Water, 癸 Gye=Yin Water.

Branches: 子 Ja Rat 23-01 Water, 丑 Chuk Ox 01-03 Earth, 寅 In Tiger 03-05 Wood, 卯 Myo Rabbit 05-07 Wood, 辰 Jin Dragon 07-09 Earth, 巳 Sa Snake 09-11 Fire, 午 O Horse 11-13 Fire, 未 Mi Goat 13-15 Earth, 申 Sin Monkey 15-17 Metal, 酉 Yu Rooster 17-19 Metal, 戌 Sul Dog 19-21 Earth, 亥 Hae Pig 21-23 Water.

Reading Junho's Earth-Heavy Chart

Let’s start with Junho, born on July 18, 1988 at 7:30 AM in Seoul (male).

Born July 18, 1988 · 7:30 AM · Seoul (male)

Junho has a year pillar of 戊辰 (Mu Jin), month pillar 己未 (Gi Mi) with Earth as the month branch, day pillar 甲戌 (Gap Sul), and hour pillar 戊辰 (Mu Jin) with Earth as the hour branch. His day master is Yang Wood (甲 Gap).

The element count across all eight characters is:

  • Wood: 1
  • Fire: 0
  • Earth: 7
  • Metal: 0
  • Water: 0

Strongest Element: Earth
Scarcest Element: Water

Given Junho’s Earth-heavy chart, his siksin and sanggwan are both heavily influenced by the Earth element. This indicates that he naturally tends to have a strong, grounded presence and can be very reliable and practical in his actions.

Understanding Siksin and Sanggwan

  • Siksin (Output Star): In Junho’s case, the siksin is derived from Yang Wood (甲 Gap). Since Wood generates Fire, which then generates Earth, the output star for this day stem is the Earth element. This means that Junho naturally produces qualities associated with Earth—stability, reliability, and practicality.

  • Sanggwan (Expression Star): The sanggwan is also determined by Yang Wood, but in this context, it reflects how he expresses his Fire-like traits to others. Therefore, Junho tends to present himself as someone who is dependable, steady, and reliable.

A Common Misconception

A common misconception is that siksin and sanggwan are interchangeable terms with the same meaning. This is not accurate. While both stars influence your life in significant ways, they serve different purposes:

  • Siksin focuses on internal strengths and natural abilities.
  • Sanggwan highlights how you present yourself to others.

For example, Junho’s siksin reflects his inherent stability and dependability, whereas his sanggwan shows how he communicates these traits in social settings. Understanding this distinction can help clarify the nuances between the two stars.

Try This: Reflect on Your Own Siksin and Sanggwan

  1. Identify Your Day Stem: Look up your birth date using a Saju calendar to find out your day stem.
  2. Determine Siksin and Sanggwan: Use the generating cycle (Wood generates Fire, etc.) to determine your output star and expression star.
  3. Reflect on Your Strengths and Expression: Consider how these stars influence your daily life and interactions.

Junho’s Specific Application

Let's break down Junho further:

  • His day stem is 甲 Gap (Yang Wood). Using the generating cycle, we find that Wood generates Fire, which then generates Earth.
  • Siksin (Output Star): Earth
  • Sanggwan (Expression Star): Earth

This indicates that both his internal strengths and how he presents himself align strongly with earth-based qualities.

Contrast Between Junho and Hana

Now let’s contrast Hana, born on January 22, 1992 at 4:40 PM in Seoul (female). Note that her saju year is still 1991 because she was born before ipchun (the start of the new saju year).

Born January 22, 1992 · 4:40 PM · Seoul (female)

Hana’s chart looks quite different from Junho's:

  • Year pillar 辛未 (Sin Mi)
  • Month pillar 辛丑 (Sin Chuk) with Earth as the month branch
  • Day pillar 丁酉 (Jeong Yu)
  • Hour pillar 戊申 (Mu Sin) with Metal as the hour branch

Her day master is Yin Fire (丁 Jeong).

The element count across all eight characters is:

  • Wood: 0
  • Fire: 1
  • Earth: 3
  • Metal: 4
  • Water: 0

Strongest Element: Metal
Scarcest Element: Water

Hana’s chart has a dominant Metal influence, which means her siksin and sanggwan are more aligned with metal qualities:

  • Siksin (Output Star): Derived from Yin Fire, Hana's siksin is the Metal element. This suggests that she naturally produces traits associated with metal—sharpness, resilience, and adaptability.
  • Sanggwan (Expression Star): Her sanggwan also reflects her Metal-like expression, showing how she communicates these traits to others.

How the Hour Pillar Adds Value

The hour pillar provides additional insight beyond what the day pillar alone offers. For Junho, the hour pillar 戊辰 (Mu Jin) with Earth as the hour branch reinforces his earth-based siksin and sanggwan, indicating a strong, grounded nature throughout the day.

For Hana, the hour pillar 戊申 (Mu Sin) with Metal as the hour branch also influences her metal-based siksin and sanggwan, highlighting her sharpness and resilience in daily activities.

What Changes When Metal Takes Over

To further illustrate the differences:

  1. Day Master: Junho’s day master is Yang Wood, while Hana’s is Yin Fire.
  2. Strongest Element: Junho has Earth as his strongest element, whereas Hana has Metal.
  3. Expression of Strengths: Junho presents himself as reliable and grounded (Earth), while Hana appears sharp and resilient (Metal).
