A Life Path Number is a key concept in numerology that represents an individual's personality, strengths, and challenges. It is calculated by adding together the digits of a person's birth date until a single digit is achieved, except for the master numbers 11, 22, and 33, which are considered special. This number is believed to provide insights into one's life purpose and direction. Each Life Path Number, from 1 to 9, has distinct characteristics and traits, helping individuals understand themselves better and navigate their life journey more effectively.
