Why one should be free in sharing spiritual information/knowledge/evolution

The amount you help someone in their spiritual evolution, is the amount of help you will receive in yours. Therefore, by sharing, you are increasing the amount of help you receive. Also you are creating a larger network people who are awakening/evolving and therefore creating a stronger global consciousness, hence not only making the entire process faster, but also making it easier for people to evolve. A stronger global consciousness is also a growing global consciousness. Thereby through the domino effect of karma, the spiritual evolution of the earth will be jump started. Then the wheels of causation will take over and propel it into a pace that constantly grows and multiplies.
