The Akashic Records are a field within the quantum field of consciousness, an energetic place where all the deeds of all the souls are stored. Some imagine their own records as a sacred temple or a great library.
Accessing the records are primarily about our intention, so if we have a high vibration of good intentions then this will affect our experience of the records and whether we will be able to access. We always have access to our own records and other souls to the extent to which they merge with our own records. An easy way to think of it is that the Akashic records are like a super computer which stores information for every soul. The Akashic records are also constantly being created, updated and added to and can provide guidance and also healing. They hold information about your spiritual lessons and evolution in this lifetime and from past lifetimes. Before you entered this physical time and space your soul made an agreement. Before you came into human form, your soul had a specific purpose or destiny that it had agreed to fulfil, this is your Soul Journey. You were sent to this dimension of Earth at a specific time, to a specific place and with a specific purpose. One thing that is never predetermined is your free will and choice. Life is full of choices. These choices are seen as our fate - we can choose which path to go down, we can choose which road to avoid and which road to pursue, but one thing that we cannot change is our destiny, for example our family of origin and our place of birth. One thing we always have control over is our own vibration and perception of any situation or challenge.
Our destiny is essentially to experience the Unconditional Love of the Universe and often this takes many journeys, across many lifetimes and dimensions, in order to fully return to this energy of Unconditional Love.
