The mind can become more neutral to the object only when understanding grows. When the mind does not judge that the experience is good or bad, the mind is neutral; otherwise liking and disliking arises all the time.

First, you need to see the mind as it is – that liking and disliking are happening all the time. Vipassana meditation object must be nature. If you try to control nature, you cannot understand nature as it is.

Slowly, after a long time, you see how the mind changes, i.e., liking and disliking become less and less because of awareness, understanding.

However much the mind reacts to the experience depends on your understanding level.
