Astrology Basics: What, How, Where, and How They Relate

Building Blocks of a Birth Chart
  • Planets = What — the core drives and functions (identity, emotions, mind, love, action, growth, discipline, change, dreams, power).
  • Signs = How — the style, tone, and archetype that color those drives (e.g., direct like Aries, grounded like Taurus, curious like Gemini).
  • Houses = Where — the life arenas where those drives play out (self, money, communication, home, creativity, work, partnership, etc.).
  • Aspects = How They Relate — the angles between planets, showing whether energies cooperate, challenge, or transform one another.
What Are the Planets?

ดาวเคราะห์ describe the core drives and “What” is acting in the chart. They are the active characters in the story, expressing themselves through the signs (How), operating within the houses (Where), and interacting through aspects (How They Relate). A common reading sequence is: Planet → Sign → House → Aspect.

What Are the Signs?

What Are the Houses?

While planets show what is acting and signs show ยังไง, houses reveal ที่ไหน this influence is felt—whether in self-identity, relationships, career, or spirituality. Understanding houses grounds astrology in lived experience.

What Are Aspects?

ด้านต่างๆ are the angular relationships between planets. They describe how planetary drives interact—whether they cooperate harmoniously, challenge each other, or demand transformation. In practice, aspects reveal the chemistry between different parts of the psyche.

What Are the Four Angles (ASC / DSC / MC / IC)

The Four Angles are the most important reference points in the natal chart. They form the "axis system" of life, defining self-presentation, relationships, family roots, and social role.

Overview of the Four Angles
  • Ascendant (ASC): The zodiac sign rising on the eastern horizon at birth. It represents outward personality, first impressions, and the way one initiates new experiences.
  • Descendant (DSC): The point opposite the Ascendant. It represents partnerships, one-on-one relationships, projection, and complementary qualities.
  • Midheaven (MC): The highest point of the chart (10th house cusp). It represents career, public image, life direction, and one’s aspirations.
  • Imum Coeli (IC): The opposite of the Midheaven (4th house cusp). It represents home, family, roots, inner emotional life, and private foundations.
Functions and Symbolism

The Four Angles divide the chart into two axes: ASC–DSC describes “self vs. others,” while MC–IC describes “public vs. private.” The signs and planets linked to these points shape how we begin, connect, ground, and achieve in life.

What Are the Lunar Nodes (North Node & South Node)

The Lunar Nodes are two mathematical points where the Moon’s orbit crosses the ecliptic. In astrology, they symbolize karmic patterns, spiritual lessons, and the path of growth.

Astronomical and Astrological Meaning
  • North Node (☊): Points toward the future. It represents qualities to develop, life lessons to embrace, and growth through new experiences.
  • South Node (☋): Represents the past. It symbolizes natural talents and familiar patterns, but also habits that can hold one back if over-relied upon.

The Nodes are not physical bodies but symbolic points. Their sign and house placement, along with planetary aspects and transits, highlight key life themes and turning points.

Interpretation Framework
  1. Sign: Describes style and qualities. The North Node sign = growth energy; the South Node sign = instinctive tendencies.
  2. บ้าน: Shows the life area where lessons unfold (e.g., relationships, career, family).
  3. ด้านต่างๆ: Planetary connections describe challenges and support in working with the Nodes.
Practical Insights
  • Embrace the North Node: Practice new traits gradually, expanding outside the comfort zone.
  • Integrate the South Node: Use existing talents without becoming stuck in old habits.
  • Watch Timing: Nodal returns (approx. every 18.6 years) and eclipses often mark life-defining turning points.
