A thought is a thing, an object, more subtle than a physical form but nevertheless an object. Feelings too are objective, they can be felt and so therefore they too are objects and also come under the heading of a thing.
When a thought is present that states there is someone or something it is simply a thought appearing in that particular way, at another time it can appear as a thought about a flower or the weather or any other topic.
There is no actual person present in a thought about a person than there is actually any sweetness or sugar in a thought about sugar, it is simply a thought.
All that is assumed to be a person doing the thinking or feeling is found in the thinking process itself, there is no actual person therefore but simply a thought or feeling about a person manifesting.
This thinking or feeling about there being a person present is an activity arising, it is action only and nothing more.
In this way it can be said that there is thinking or feeling but no thinker or feeler that is prior to the action, or during it, appearing to be responsible for it.
These action are not responses to anything, they are simply appearances that have no prior producer or creator. They are simply manifesting from nowhere, from nothing.
One such thought manifests as the idea that there is someone witnessing the thoughts but upon closer scrutiny this action too can be seen to be yet another action only. When looked at closely all that is assumed to be a someone is no more than action manifesting as the play of mind.
The witnessing of the presence of these actions is not done by anyone at all, they are simply witnessed. That which witnesses the actions is itself a non-active presence which is absent of any qualities whatsoever, lacking any qualities of any sort it is absolutely nothing. This non-objective presence is what the imagined person actually is. A person is an idea, a thought arising and nothing more than that.
