Hey swetha
for me numerology is easier to understand than astrology, yet I do follow both. I started with astrology because it was easier to find info... but numerology is catching up fast!! As for LP (life path) ... of all the studing I have done this number stands out the most and is the foundation for the rest of your numbers. Numerology has more than one system so it can get confusing, however it's really no different than the different astrology systems.
As to dubble digit life path numbers - the only two I use are the two master numbers of 11 and 22.
