It is said that the past and the present are deeply interwoven when birth marks are indelibly imprinted onto an individual's physical body. This happens for two reasons. One, the body has not had enough time between its incarnations to heal properly. Two, the mind needs to reconnect with the past life trauma so it can be healed and released. So a birth mark is formed at the site of the past life damage when the individual chooses to reincarnate into a new life.
Some researchers like Walter Simkew, MD and Jim Tucker, MD believe past life birthmarks appear because the soul's mind, which is not part of the brain, has a blueprint that exists after death. This blueprint is used to create the fetus in the next incarnation, which may lead to birthmarks that correspond to past life trauma.
Epigenetics is showing that experiences in life can leave scars on the genes that will be passed on to one's descendants. Pregenetics refers to genetic code that precedes life - possibly from past lives. An article from the International Journal of Yoga on genetics, epigenetics, and pregenetics includes information about past life influences on current physiology. According to the article, "...brothers and sisters are unique individuals with different perspectives and ways of life. Although they genetically and even epigenetically share the same or similar environment, we still find them different and unique." The article goes on to note no explanation exists for such an anomaly based on epigenetics, so some other factor must exist to explain such variations, and this might be pregenetics, or imprints from past lives.
Birthmarks have been around as long as there have been people. Some are considered evidence of previous incarnations. Some people just believe they are nothing more than a physical trait. Just because a person has a birthmark doesn't necessarily mean it's tied to a past life trauma in every instance, but for some this may prove to be true, as there have been many past life regression cases with correlations to birthmarks. There are also many different types of birthmarks, each thought to have their own meaning. #Consciousvibrancy
