What does a spiritual experience mean? If you are a Christian sitting in church, it might mean that Jesus Christ survived his death and has taken a personal interest in the fate of your soul. If you are a Hindu praying to Shiva, you will have a very different story to tell. Altered states of consciousness are empirical facts, and human beings experience them under a wide range of conditions. To understand this, and to seek to live a spiritual life without deluding ourselves, we must view these experiences in universal and secular terms.
