Holistic experience.
One of the things I did when I first started my reiki journey, was try to analyse every vision, every colour, every sensation I felt, trying to understand and create a meaning behind each experience.
When I think about why I might have done this, the reason is simple. I was searching for an answer, I was so desperate for guidance that I forced everything to have a significance.
When you are looking for answers in this manner, firstly it is easy to interpret signs and symbolise in a way that suit your needs and agenda at the time. Secondly, reiki is about the holistic experience, there are messages and guidances that can be delivered during a session, and if that is the case, they will be acknowledged, but it is important to be open and allow what comes and goes during a treatment to do just that. It is also good to know that similar to dreaming, many visions or sensations will be forgotten during the treatment, and that is okay too. You will remember what will serve your highest good at the time, and everything else will simply pass on by, like clouds in the sky.
Know that you are receiving whatever you need at the time, and that this is coming from a loving place full of healing.
