When family members die, we pay tribute to their lives by offering flowers at their grave, by publishing kind words about them in their memory in the obituary section of a newspaper or hanging the photograph of the deceased in one’s house. However, all these have no significance in helping our ancestors in the afterlife.
Through spiritual research we have found that any one of us can become a ghost. The desires, cravings and attachments we have during our life on Earth if not controlled and overcome, become our weak point in the afterlife. Higher level negative control lower level ghosts in the afterlife.
