What is illumination?
Soul-Realization (Self-Realization) is nothing more than the incarnated soul (lower self or personality) realizing that is not the body and is one with the Higher Soul (Higher Self). This is the meaning of yoga or illumination. There are many degrees of illumination. For some people, it may take years before they experience an initial glimpse of illumination or Buddhic consciousness. Others may take months and others may take weeks.
