In Reconnective Healing, is the concept of “reconnecting strands and reconnecting strings” another description of working not on DNA, but interdimensional DNA and the morphogenetic field, to restore soul attributes to effective levels of expression? Or is strings referring to cordings, and strands to interdimensional DNA and/or the morphogenetic field?

You have hit on the true mechanistic basis of this insight that was perceived intuitively by the founder of this healing modality. Cordings are a key karmic organizer, and consequence as well, of both good and bad intentions. But achieving freedom from past trauma will necessitate dissolving the negative cordings and healing the karmic underpinnings. Otherwise, the cords will reform. So dealing with cords, in this case termed strings is likely to be a temporary benefit because the underlying karma will not have been healed thoroughly. As such, it is an energetic modality that will only go so far in dealing with severe issues and is not an ultimate answer for thorough and complete healing. Dealing with missing strands to help restore a better connection to the soul's projection of attributes, and the configuration of the individual in their morphogenetic field, will help repair defects and make the soul configuration for the incarnation underway function better, and may reawaken suppressed capabilities and bring an overall strengthening for the individual. The difficulty with this modality is it is restricted to this metaphor with its focus so greatly, that it will miss many, many, other things needing attention, and even those it wants to focus on are so ill-defined that it is impossible for the healer to hold a precise intention that would guide the divine realm to do what is most needed.
