Stream of Thought

I was taking a yoga class recently and the teacher was reminding us that we are not our thoughts. Instead, she said that our thoughts were like a stream...and we could choose to wade in that stream, or simply observe it passing by. I loved this metaphor, since I know I tend to get very wrapped up in my thinking and beliefs and perceptions.
When we release ourselves from being "attached" to what we think is true, we can then appreciate other viewpoints and we develop a flexibility in our thinking rather than being rigid and stuck. This is a constant journey, to let go of the need to be "right" and in control, and instead, be open to the possibility that things are just not always as we'd like or think them to be.
