Pronology (ध्वनि ज्योतिष) is the study of names and the vibrations they produce, the study of how name vibrations influence one’s personality and life and the study of even how even slight changes in names can lead to great success in life.
Pronology (ध्वनि ज्योतिष) is indeed a rare science and is not a matter of interpretation alone. It is the study of sounds or phonetics in combination with alphabets in your name plus the combination of astrology and calculating the lucky number based on alphabets one uses to spell their name with.
