Questions for Self-Inquiry

Where do our feelings and thoughts arise, appear, and vanish? There must be something that is not in movement in order to become aware of these states.

We experience time (i.e., past, present, and future) but how is it possible that we can become aware of these if we are a part of them (i.e., the observer would be part of the observation)?

Where is that continuous self-awareness (i.e., I am) that is
ever present?

How is it possible to do self-inquiries for ourself? That means that the observer is observing himself or herself (e.g., an eye trying to look at itself).

Why can we change but our awareness of ourselves stays?

We build our world from five external senses—what is it like with more senses?
