What Does a Single Crease in the Palm Mean: The Simian Crease

While the majority of people possess three distinct palm lines - the Life, Head, and Heart Lines - approximately 5% have a single prominent Simian Crease crossing their palm in place of two separate lines. Only 2% exhibit this trait on both hands.
This unique marking is called the Simian Line, Monkey Line, or Buddha Line. The term "Simian" is used because primates often have a single palmar crease, which may indicate an evolutionary regression, similar to a vestigial tail.
Medical studies link the Simian Lines to Down syndrome, but in reality, many healthy, intelligent individuals also have it. Palmistry also refers to it as the "transverse fold," "horizontal fold," or "blocked hand."
The Buddha Line nickname comes from statues of Buddha, which often depict a single crease instead of separate Heart and Head Lines. This raises an intriguing question: Do people with a single palm Line carry a special purpose?
What does the Single Palmar Crease look like?
The Line forms when the Heart and Head Lines merge into one. This fusion means emotion and intellect are deeply intertwined in the person’s nature.
Typically, one side dominates:
- If the line leans toward the Mind Line’s usual path (center of the palm), logic prevails.
- If it follows the Heart Line’s trajectory (upper palm), emotions rule.

Different sources offer different interpretations. One theory suggests it forms when one line (often the Heart Line) breaks and fuses with the Head Line.
Some palmists believe the Simian Line in palmistry indicates heavy karma, either unresolved past-life debts or a soul choosing a difficult path. It also appears more often in people with congenital illnesses or physical conditions.

Right or left hand?
The presence of the Simian Line in palmistry may be temporary rather than permanent. For right-handed people:

If the Simian Line is on the left hand. Individuals usually function normally, exhibiting emotional or mental differences only under exceptional circumstances.
-
If only on the right (dominant) hand. Any mental or emotional challenges are likely to develop later in life rather than being innate.

Famous people with Simian Crease
Meghan Markle, Hillary Clinton, Robert De Niro, Tony Blair, and Henry Miller all possess the Simian Line. These individuals tend to be highly sensitive, intensely focused, and remarkably stubborn. They typically achieve what they set out to accomplish.
However, famous people with Simian Line may develop tunnel vision regarding their goals, operating on the principle: "I don't always notice my surroundings or circumstances while pursuing my objectives."
Palmists observe that Meghan Markle's Simian Line meaning (both hands) indicates her potential for significant accomplishments and high achievement.

Additional signs for the Single Palmar Crease
-
Fate Line
For those with a Simian Line, a well-marked Fate Line on the palm is considered a positive indicator. Such a pattern on the palm means that the person will not blindly follow emotions. Logical arguments of other people will be perceived as a reasonable argument, and not a reason for a dispute. -
Belt of Venus A visible belt of Venus indicates the sensitivity of the owner of the Simian Lines and the ability to perceive the feelings of other people. This feature proves most favorable when the horizontal line appears lower on the palm.
-
Life Line Connection with the Life Line enhances the influence of the transverse strip. While the three main lines cannot fully merge, they may intersect beneath the index finger. The bearer of such a pattern on the palm will have to overcome obstacles on the path of life.
-
Cross & star Unfavorable signs (crosses and stars) on the palm can indicate a predisposition to criminal behavior.

Palm reading Simian Line: conclusions
Approximately one in a hundred people shows significant deviations in their primary palm lines. The standard configuration forms an "M" shape with Life, Head, and Heart Lines connected by the Fate Line.
When these traits merge or distort, creating powerful connections between emotional and mental energies while breaking their natural patterns, it creates an anomaly.
Such deviations, as the Simian Crease on both hands, typically manifest as either extraordinary gifts or significant challenges, demonstrating how exceptional traits can produce either remarkable talents or substantial difficulties.
