TL;DR: Sha are the land forms and hills surrounding an acupuncture point, serving to shield and retain qi. Analyzing the shape, position, and gathering or dispersing tendencies of Sha determines the success or failure of a land point, requiring meticulous observation and evaluation.
What is Sha in landform feng shui?
In the theoretical system of Landform Feng Shui (also known as Form School), identifying and evaluating a good land point relies not only on the Dragon (the mountain range approaching) and the Point (the location where qi gathers), but also heavily on Sha (surrounding land forms). Sha, along with Dragon, Point, Water, and Direction, form the immutable Five Decisions that any Feng Shui practitioner must master. If the Dragon is likened to the "parents" giving birth to the point, then Sha are the "fence" and "city walls" that protect and shelter the point from harmful qi and toxic winds from outside.
The concept of Sha in Feng Shui originates from observing actual terrain. The ancients noticed that places with clustered terrain and surrounding mountains were often good for settlement, less affected by natural disasters, and had mild climates. From this, they generalized the principle: an ideal land point should have surrounding land forms on all four sides, collectively called Sha.
Table classifying Sa by position and shape in Loan Đầu feng shui.
| Type of Sa | Position | Role | Good characteristics |
|---|---|---|---|
| Án Sa | In front of the huyet, directly before it | A screen blocking directly | Round, harmonious, moderate distance |
| Triều Sa | In front of the huyet, farther than Án Sa | Creates a majestic scene, increases the strength of the huyet | Winding, facing the huyet as if paying homage |
| Left Thanh Long | To the left of the huyet | Protects the huyet from bad qi from the side | Gently winding, slightly higher than Hổ Sa |
| Right Bạch Hổ | To the right of the huyet | Protects the huyet from bad qi from the side | Slightly lower than Long Sa, with a submissive bowing posture |
| Hậu Sa | Directly behind the huyet | A solid support for the huyet position | Tall, sturdy, round or like a turtle shell |
| Cát Sa | Surrounding the huyet | Gathers good qi | Harmonious, embracing, lush, balanced |
| Hung Sa | Surrounding the huyet | Carries killing qi, causes disaster | Sharp shape, turned-away posture, desolate |
What does Sha mean in feng shui?
What is Sha?
Sha (砂) literally means sand or soil, but in Feng Shui, Sha refers to all terrain features and objects surrounding the point. These can be mountains, hills, mounds, or even man-made structures such as houses and walls (in urban Feng Shui). Sha acts as a natural "shield," preventing strong winds (killing qi) from blowing directly into the point, while also being a place where vital qi (yang qi) gathers and is retained. A point with good Sha creates a secluded, cozy, and safe space, helping people living there to be healthy, peaceful, and prosperous.
What is the role of Sha in the Five Decisions?
In the fourfold set of Landform Feng Shui, Sha holds a crucial role, considered a decisive factor in the success or failure of the point. If the Dragon is the energy source from afar and the Point is where energy converges, then Sha is what keeps that energy from dissipating. A point with the best dragon vein, if surrounded by open space without Sha for shelter, will have its qi scattered by wind, becoming a point of dispersed qi, losing its significance. Conversely, if Sha surrounds it tightly and the mountain forms embrace it, qi will gather, creating a place of prosperity for future generations.
How is Sha classified by position?
Based on relative position to the point, Sha is divided into various types, each with its own function and meaning. This classification provides a more detailed and systematic view of the terrain.
What is Facing Sha (An Mountain)?
Facing Sha is the mountain or hill in front of the point, directly ahead. It acts like a screen, blocking direct views too far away, creating a sense of safety and seclusion. A good Facing Sha is round and harmonious, at a moderate distance, not too high to obstruct the view, nor too low to lose its effect. Its shape can be like a full moon, a rectangle, or an equilateral triangle, depending on the specific terrain.
What is Court Sha (Court Mountain)?
Court Sha are mountains or ranges farther away than Facing Sha, in front of the point but at a greater distance. Court Sha create a majestic backdrop, enhancing the point's status. Beautiful Court Sha often form a winding mountain range facing the point as if paying homage. The presence of good Court Sha indicates the point has broad connections and links with the surrounding region, bringing prosperity and good fortune.
What is Dragon and Tiger Sha?
These are two mountain ranges or hills on the left and right sides of the point, likened to two arms embracing the point. Dragon and Tiger Sha play the most important role in protecting the point from harmful qi from the flanks.
- Left Green Dragon (on the left when looking outward from the point): symbolizes masculinity, power, and wisdom. A beautiful Dragon Sha should have a soft, winding form, slightly higher than the Tiger Sha but not overly dominant.
- Right White Tiger (on the right side of the point): symbolizes femininity, strength, and protection. The Tiger Sha should be slightly lower than the Dragon Sha and have a bowed, submissive posture.
The relationship between Dragon and Tiger Sha must be harmonious and balanced. If one is too high or strong compared to the other, it creates instability, causing issues for those living in the point, such as disputes and family conflicts.
What is Back Sha (Black Tortoise)?
The Back Sha is the mountain or range directly behind the point, serving as a solid backrest. The Black Tortoise symbolizes longevity, stability, and protection. A good Back Sha should be tall and sturdy, providing absolute safety. Its shape is often round or tortoise-shell-like, bringing peace and durability.
How is Sha classified by shape and meaning?
Besides classification by position, Feng Shui masters also classify Sha based on shape and stance, inferring auspicious or inauspicious meanings.
What is good Sha (auspicious Sha)?
- Harmonious, rounded shapes: soft forms without sharp edges, bringing comfort and peace.
- Embracing posture, facing the point: ranges that surround and face the point as if protecting it, creating good qi convergence.
- Lush and clean: covered with green vegetation, not eroded or barren, indicating abundant vital qi.
- Balanced and proportionate: sizes and heights are balanced, creating a solid, stable whole.
What is bad Sha (inauspicious Sha)?
- Ugly, sharp shapes: bizarre forms, pointed like spears or blades, or with sharp angles, considered to carry killing qi.
- Betraying posture, turning away: ranges that turn their backs to the point or point sharp tips toward it, seen as omens of disaster and illness.
- Desolate and ruined: eroded, withered vegetation, or signs of destruction, indicating no vital qi and hidden risks.
- Imbalanced: excessive disparity between Sha types, e.g., Dragon Sha too high while Tiger Sha too low, causing instability and conflict.
How does Sha affect a home?
How does Sha retain qi and block wind?
The most fundamental principle of Sha is "hiding wind and gathering qi." Qi (vital energy) is a subtle, invisible energy easily dispersed. Wind is seen as the destroyer of qi, carrying it away. Thus, a good point needs Sha around to block wind and keep qi from being blown away. The Sha ranges, especially Dragon and Tiger Sha and Back Sha, form a natural "fortress wall," shielding the point from strong, harmful winds while creating a calm, warm space where qi can gather and circulate slowly and steadily.
How does Sha affect energy flow?
Sha is not merely passive in blocking wind; it actively guides and directs energy (qi) flow. The shape, stance, and direction of Sha ranges create different vortexes, convergences, or dispersals of qi. Ranges with embracing postures facing the point create a vortex drawing qi to the center, strongly concentrating it. Conversely, ranges with betraying postures or broken shapes create chaotic qi flows, causing disturbance and instability.
How does Sha influence human destiny?
According to Feng Shui, terrain and living environment directly affect the fortune, health, and wealth of inhabitants. A point with good Sha creates an ideal living environment, helping people feel safe and comfortable, leading to clear minds and robust health for work and growth. Conversely, a point with bad Sha creates instability, causing anxiety and negatively impacting health and relationships. However, it must be emphasized that Feng Shui is only one factor among countless influences on a person's life and should not be absolutized.
How do you observe and evaluate Sha?
What are the steps in the overall observation process?
Evaluating Sha requires meticulous, systematic observation. First, the practitioner stands at the center of the point (or intended point) to survey the surroundings. Identify the positions of all Sha types: Back Sha, Dragon and Tiger Sha, Facing Sha, and Court Sha. Then, observe their shapes, stances, distances, and interrelationships. Observations should be made at different times of day and weather conditions for the most accurate view.
Detailed evaluation criteria
- Distance: from the point to each Sha must be appropriate. Facing Sha should not be too close (causing oppression) or too far (losing its shielding effect). Dragon and Tiger Sha should embrace the point but not be too close (causing pressure).
- Height: heights should be proportionate to each other and to the point. Back Sha is usually tallest, then Dragon and Tiger Sha, then Facing Sha. Excessive height differences cause imbalance.
- Shape: should be harmonious and soft, avoiding bizarre, sharp, or broken forms.
- Stance: should face the point, creating an embracing, protective posture. Avoid betraying, turning away, or pointing sharp tips at the point.
- Physical condition: Sha should be covered with green vegetation, not eroded or barren. Areas with bad Sha often show signs of desolation and ruin.
