It becomes a part in an accumulative form. As life goes forward it will always build and become useful. We are the ones that developed in the perfect realms of development and perpetuated ourselves to become a model life with the greatest responsibilities to care for others. We became the caregivers for all other life forms. The greatest party of development becomes the greatest promoter for ALL others.
Life gives possible choices.
But the greatest choice is sometimes the inability to function by oneself, and then it becomes a member of a group establishment. Somewhere in all life is the first life starter. Some are then unable to advance by themselves. Look at life and wonder what gave you the opportunity to become a body with the ability for the enormous movement. You are never alone to become something, and always a helping hand in all movements.
