Genetics control physical aspects of a being’s incarnation. Whereas spiritual connection extends before and beyond the parameters of physicality. Genetics are a method or modality to manufacture or manifest the physical nature of a spiritual being. Other than sharing the successful genetic coding to create a physical being – there isn’t necessarily or usually an extraordinary spiritual connection beyond a localized familiarity that is inevitable. Of course the natural connection between every being is obvious – but the additional layer of connectivity is not enunciated by physical proximity, it is incidental.
Incarnation on earth is a manifestation to celebrate a spiritual being’s connection to all that is, using the modality of the physical world.
