This is how I see them, I am still learning and there is much still to be learnt about the orbs in photographs.
There have been many books written about the orbs that are appearing in photographs all over the world, many of them related to orbs being spirits, others articles see them all as dust, moisture, camera artifacts etc or both. When a bright orb such as this appears in my camera screen there is awe and wonder. I keep an open mind regarding the phenomena and have had insights that some orbs are from other dimensions.
As I am writing another book about orbs, even though all of the above I feel is correct, I would like to know if anyone else has had experience with orb energy. I have spoken to several people who have actually seen orbs with their naked eye or in visions. Many others are reluctant to talk about orbs not being of an earth form (spirits), due to what other people, even friends, may think of them. I know that we all have different perspectives and I enjoy this human experience as we all see differently and our mind usually gives us a picture as we have learnt. An open mind however will reach out and a different picture, the first thought, sometimes give to orbs a face in truth - a symbol or symbolic gift for our heart and a peace is known to us. A gift is to give and with our heart we share love in orb-light which seeks out minds' light.
