“THAT is very difficult. This is the old trouble when you have to define the words you use. We are all part of the same spirit because spirit is the substance of life. Soul, for the purpose of strict definition, is individual spirit. So in these terms, all life is one, but spirit being infinite has an infinite variety of manifestations.
Spiritually we are all one, but our souls are individual. In your world people group together. They combine for specific labour or service. In our world there are groupings to achieve functions which are part of the plan. Some of these groupings are not so intact – it is very hard to find words for spiritual conditions – as others. Speaking generally, when there are group souls there is a kinship or affinity between those individual souls in your world.” ~ The Silver Birch Book Of Questions & Answers, P.41
