As per the Oxford dictionary, Numerology is the branch of knowledge that deals with the occult significance of numbers.
In numerology, Astrologer relates each number and alphabetical characters to a particular number and believes that the particular number has some sort of cosmic vibration. As per Hindu astrology, Astrologer builds a relation between numbers and alphabetical characters to a particular Number from 1 to 9 and each number from 1 to 9 is represented by Planets. For example Number 1 represented by Planet Sun, Number 2 represented by Planet Moon, etc. These planets (1-9 numbers) are influencing individual’s characteristics.
