Thought Training, Incubation and Meditation Upon Death

The Ancient Greek Healing Tradition called Incubation. Incubation was also a spiritual practice.

Question: I have been meditating for many years, and I have had a lot of benefits from it, but now I seem to have reached a point where there doesn´t seem to happen anything further. I can´t stop my thoughts, they keep on repeating the same themes. How can I progress further? 

Meditation as an Art of Life - The Ancient Logos

In my book A Dictionary of Thought Distortions I claim that the Sophists used thought distortions as a way of getting on in the world, while Socrates (the philosopher), used critical thinking. I consider this book to be a kind of philosophical diary on how I, during my spiritual crisis, used critical thinking (elenchos, the art of refutation) to distinguish base magic (New Age), which leaves everything to chance, and may lead its practitioners to consort with falsity and evil daemons, and higher magic or theurgy.
