What is the Triangle Mark? Where is it located on the hand?
The triangle mark is not a separate palm line but rather a triangular shape formed by the intersection of the major lines in the palm. These natural triangles can appear in various locations, each associated with a different meaning according to traditional physiognomy.
Below the Ring Finger (Wood Star): This is the most common position for the triangle mark. If a well-defined triangle appears here, it is called the “leader mark,” suggesting that the individual possesses leadership qualities and is easily trusted and valued.
Below the Middle Finger (Earth Star): When a sharp triangle, like a seal, appears in this position, it is referred to as the “stability mark.” People with this type of mark tend to work steadily and calmly, especially as they gain experience from middle age onwards.
At the Intersection of the Three Major Lines: If the triangle is located between the life, intelligence, and career lines, it is known as the “palm treasure seal,” symbolizing a stable life path with fewer significant upheavals.
However, if the triangle mark appears close to the emotional line and is disordered or unbalanced, it is considered a sign of emotional turmoil and potential challenges in relationships.

“Rich until ninety-nine” – Science or Superstition?
From a scientific perspective, palm lines form in the fetus and remain largely unchanged throughout life. Therefore, the belief that palm lines can accurately predict the future lacks a solid basis. However, triangles in nature are the most stable structures, widely used in architecture, from pyramids to traditional East Asian buildings.
Thus, associating the triangle mark with stable fortune and wealth, as suggested by the phrase “rich until ninety-nine,” is primarily symbolic. It represents a longing for a stable, peaceful, and less tumultuous life—an expression imbued with optimism and faith in the positive aspects of life.
Palmistry: A Quiet Health Indicator
Aside from its metaphysical implications, ancients also considered palmistry a way to monitor health. They believed that the color and lines of the palm could provide insights into one’s well-being:
Rosy palms: Good blood circulation.
Pale palms: Possible indication of anemia or low energy.
Red and hot palms: Potential warning sign of high blood pressure, liver issues, or metabolic disorders.
Palm lines can also reflect one’s mental state:
Complex emotional line: May indicate emotional instability.
Clear and regular life line: Suggests good physical and mental health.
Even fingernail moons, skin tension, and palm line clarity were thought to provide clues about digestion, circulation, and stress levels.
Palmistry: A Cultural Practice, Not Destiny
Clearly, the saying, “Those with a triangle mark will be rich until ninety-nine,” should not be interpreted superstitiously. Instead, it is a symbolic folk expression that encapsulates the desire for a fulfilling, peaceful, and long life.
In modern times, what matters most is adopting a scientific approach to life, cultivating healthy habits, and understanding that happiness and success result from daily choices and efforts rather than predetermined by palm lines.
