Is Mindfulness the same as having an Observer?

If this was bone-obvious to everyone else, then silly me, but I just thought of it because I heard these two words separately long ago and connected them while answering another question... **Are "the Observer" and the process of being Mindful, in essence the same thing? Does one involve the other inherently?** I have used them differently and never connected them before, because I thought: 1. *The Observer* is a developed system within "me" (which is a collection of points of view of varying levels of awareness) and not everyone has an Observer or is aware of it all the time. 2. *Mindfulness* is something I *do* and is not the activity of another point of view within "me". But, trying to be mindful when I have only one point of view is not very possible, and who would be mindful, other than the Observer? Finally: is transcending the Observer (and the need for Mindfulness) the same as Nonduality? I think it is. (Don't worry about answering this question, it is just an idea.) **EDIT:** My Healing Teacher said that I have to get people to "define their terms", so here are my definitions: **The Observer** is the *experience* of being aware of myself. It feels like I am witnessing my own thoughts and actions. **Mindfulness** is the *process* of being aware of what I am doing. (To me, this does not require an Observer, but that is what I am asking.) **"Being aware of myself"** means... Well, that I know what I am doing right now. Different from the other two. **A Mind** - is something that *could do otherwise*, it exercises choice on some level. **Awareness** is the action of a sufficiently developed mind. **Consciousness** is awareness of being a self. **A Self** is something that knows it is a self, and that other selves know, etc. (Don't even get me started on the idea of Mind*full*ness being a way to *empty* the mind!) Has this made it any clearer what I am asking? Please try to use words such as these for an answer, supplementing with the appropriate Buddhist terms. **ADDITION:** here are some links which I hope can help people understand what I am asking: 1. This RYUC one is a bit of a muddle, but the Observer corresponds with what I am asking about, and also is similar to what I call a Neo state. The Witness is more like how I would describe nonduality. 2. This one about Energy Healing says that "In Buddhism, developing the witness/observer is a foundational piece of their teachings." Ha! 3. In this one , they use the words observer and witness interchangeably.
