I think I just found something important in my meditation practice. Kabat-Zinn had a metaphor in his book, that I really liked but then I completely forgot about it. He said that meditation is like sitting out to the banks of the river of our thoughts for a while, instead of flowing with the river. Just watching and listening to the river and its constant flow, without letting it carry us away. Whatever happens inside the river, it is nothing more than a thought, not the absolute truth. When we feel something, it is not more than just a feeling. When we think something, it is not more than a thought, generated by our mind. And it really is possible to look at thoughts as mere thoughts, feelings as mere feelings, just watching them, accepting them just the way they are, and not letting them have too much power on us.
