The name you have in this world is your first identity for your entire life in this world and unfortunately it is not your choice (it is the choice of your parents.......).
Naming of a baby is always he prime most thing to be done after birth. A question arises here. Does the name is in harmony with the his/her life and in synergy with planetary positions at the time of birth? The name has to vibrate very well in the ongoing life on Earth. Hardly any people look at these aspects.
Vedic Astrology suggests first letter of the Name as per the birth time Lagna/ Moon Sign (considering whichever is powerful). I would recommend naming a baby in a combined approach of Vedic Astrology and Numerology which is proven. Refer the table below to get an Idea about this.
Then we shall look at the Numerology aspect in the naming method. Refer the table below for knowing the number to corresponding alphabet.
Likewise, there are letters associated with Stars (incl different padas 1,2,3 & 4) and Planets. It is very much easier to get names after considering these. I have not given the procedure and calculations here since it requires a good amount of considerations on Astrological and Numerological aspects conforming in naming a baby.
Therefore it is always good to consult a learned Astrologer before naming a baby.
