Watching a Healing Afterwards, Does it Have the Same Effect?
It makes no difference to the effect of the healing whether you are participating in it at the time it takes place or watching it afterwards. You have multiple bodies and each body is in a different dimension (reality), such as physical dimension here on earth, astral dimension, etc. These dimensions and therefore bodies are timeless.
Since you do not work on your physical body with a healing, but on your other bodies, this is timeless. And you can look at this physically at another time.
