Imagine a Sun in your chakra . let it shine more and more, until it's so bright the light shines within and around you. Sunlight is the most positive light, where no negative energy can reach you anymore.
This is what finding your vocation in life is all about. When God created us, He put a desire within our soul for Him- for a purpose in this life. And when we discover that purpose and use it for His glory. our soul shines.
