We are sorry for your loss. His soul is free. I believe as soul, when we translate (cross over, die) that our essence or energy we call soul stays close by to comfort other souls through intuition and syncrinocity and when soul is comfortable to do so, it will leave and go to the place of healing and reintegration with other souls of its family group. There is no proof or disproof, but intuition and times will arrive when you can feel or sense across the veil.if you are open minded, you will “see things” and “sense things” perhaps of a spiritual nature. If it ever happens, I would love to hear from anyone. May the blessings be.
