Hi Parag,
I've generally worked with om mani padme hum, also - om shree shainaish waraya swaha,
om gum ganapeeti yea namaha. In terms of luck, the most dramatic examples I've witnessed have come from feng shui - if done correctly, the results can be quite dramatic. If you need clarity re: your career path - there are a few things you can meditate on to give you clues 1)what did you love to do as a child? Dance, sing, sports - children are generally closer to their soul's path than adults 2)what activities give you a rush of energy? 3)what activities make you lose all sense of time? For example, you might be painting and look at your watch and realize 5 hours have elaspsed and to you it felt like 5 minutes 4)what skills came easily to you as a child These are some clues to your life's path Rachel
