Within cells DNA is organized into long structures called chromosomes.  During cell division these chromosomes are duplicated in the process DNA replication  providing each cell its own complete set of chromosomes. DNA contains the genetic instructions used in the development and functioning of all known living organisms. All our cells hold all of the memories of all our lives from the beginning of time. Our microscopes may not be able to see small enough to the subtler energies of spirit , etheric, astral and emotional content within our DNA, however with practice we can intuit and communicate to our DNA. After all, DNA is the container and memory and blueprint of Spirit's design on the physical level.  DNA communication occurs in a healing using body's own intelligence to move blocks and revers dis-ease. Further DNA communication occurs in accelerating body frequency for ascension. Some symptoms that may occur in this work is if a person is more aligned with emotional and physical intelligence vs cerebral intelligence and they may have more physical discomfort in the ascension process. This is because affinity for emotions including negative and toxic emotions that NEED to be acknowledged are respected by emotional and physically intelligent people as they function from that emotional and physical alignment.
