Good to read your thoughts and experiences, Cal. As you may know the experience of deep meditation is called 'samadhi' in the Indic religions; whereas, it is called the 'Holy Spirit' in the Abrahammic religions.
The one aspect of the Abrahammic religions that is different from the Indic religions, is an understanding that the Holy Spirit can take over our life and radically change it, often times without our willing consent. I see this happening for quite a few of the people who have posted their case histories here.
The one thing that is true of all religions, is the more we submit, take refuge, surrender to the experience of deep meditation AKA 'samadhi,' AKA the 'Holy Spirit' the more the transformation, and the more rapid the transformation. So, we get to put our foot, somewhat, on the brake and the accelerator peddle to decide how rapid that transformation is going to be.
However, once we have made contact with the 'Holy Spirit' the transformation is often times inevitable. We may even participate in the demonizing of the mystic who guided us, but still end up fully submitted to the holy spirit, whether we like it or not, like Paul.
