Does my client need to give things away to others in order to grow his business, as people around him have been telling him?

This is simply not the case. It is not the reason for this pause in growth nor will it be the answer to a resumption and increase in growth over time. It will be more of a distraction and an impediment because of time and money diverted that are sorely needed to balance everything and do all that will be needed to have everything in place to implement his business and vision. His growth is not being limited by the universe in response to a neglect of charitable duty. It is limited only by lack of further diligence, working on the business itself, and those things needed for the expansion to take place in a practical way. He has the blessings of the Divine in all his business undertakings.
