If you feel as if pieces of your soul have been ripped out or that you lost your little soul (child self) due to accidents or other traumatic incidents, and therefore are feeling sick or disoriented or frightened or somehow otherwise disabled by it, I recommend a soul retrieval.
If you lost your „big soul“ (higher self or astral self) immediate action should be taken in retrieving it, because according to Peruvian shamans this can be a life-endangering situation.
A soul retrieval is best performed by a chosen in its community known shaman, healer or witch, but if you have no access to a shaman you can try and conduct a soul retrieval by yourself as described as follows:
On my spirituality and spiritualized „psychos“ blog-site pages there’s a meditation technique called „My way of Meditation…“ which you can perform with a slight variation:
If you say the prayer to your guardian angel, tell it in the prayer that you want to restore your soul or to find your little or your big soul again. Then revisit the situation where you know or felt the incident happened in your mind by visualizing the situation. If you can’t think of that situation if you’ve forgotten or don’t know exactly where or when it happened, empty your mind and wait for the angels to give you the picture/vision of that situation. Now breathe in („the situation“) the pieces of your soul or ask your angel to get the lost pieces in order to fix you and breathe out the hurt, pain and bad energies. Repeat that as long as necessary. If you feel better and done, slowly come to an end of the meditation and say praise and thanks to your angels and dear god.
Maybe drink something you like most (maybe not alcoholic beverages) and try to sleep a little.
