Individuals Do Not Possess an Exclusive Spirit
Even though I have clarified this issue in the “Dynamism of Creation,” once again, I mention it here that the spirit of beings (be them human or animals) is not exclusive. Instead, the spirit is one united, consistent, and connected force that has embraced all the universe. Each being employs this general and universal spirit according to their talent and body organization and mental mechanism. Just as if various electric appliances (be them small or big) each utilize electricity according to their specific mechanism, internal organization, capacity and force.
So, after spiritual promotion (death), the spirit does not exist for a person exclusively. Instead, it is that very eternal and imperishable universal spirit that all beings employ in any state of life.
