Past life regression uses a number of methods to encourage the mind to draw back the veil of separation between our subconscious, which remembers earlier parts of our existence, and our conscious mind.

This journey back to earlier incarnations of our soul illuminates our personality and character traits much more brightly, and brings about great healing both emotionally and sometimes physically too.
