Palm reading answer
What does a triangle on the fate line mean?
What this means
First confirm that the mark is a clear three-sided shape on or touching the vertical fate line, not random crossing wrinkles or a photo artifact.
Palmistry often reads fate-line triangles as favorable because they can point to skill, knowledge, planning or a concentrated career period.
Compare whether the fate line continues clearly after the triangle, plus the head line, sun line, support lines and both hands before drawing a strong conclusion.
