Cravings Arising to Consciousness I noticed that I usually think in a very abstract manner, without images, just words and ideas. When I try intentionally to think visually, only then does lustful or worry-related images pop up. And, only then can I seemingly redirect my attention from these images. 

If a person thinks very abstractly, is it possible that cravings or worries don't arise in consciousness? What is going on here?
I believe Tibetan Vajrayana lays more emphasis on visualization as against abstract thinking, as a means towards final liberation. Recommend utube  discourses by Professor Robert Thurman and Lama Govinda's classic 'Foundations of Tibetan Mysticism' for starters. Its likely to be a long haul.
