The word mindfulness itself is a poor translation of the Pali word 'Sati'. The Pali word actually means 'remembering to be aware of the objects that your mind is attending to'. There is no word in western languages to capture that phrase and hence word 'mindfulness' was used to convey in a confusing manner what 'Sati' means.

I have been meditating for 1 hour to 1.5 hour every day for several years and I finally got into a stage called 1st Jhana, where your mind becomes temporarily free of all 'wants' and is completely at peace. In that state the awareness becomes super sharp, breathing becomes very shallow (less than 5 breaths per minute) and experience of time distorts. Your awareness can clearly watch thoughts coming up like 'lava bubbles' from your subconsciousness into your consciousness. It is at that point you get a glimpse into 'anatta' (non-self). The idea that there is no controller (or soul or self) that is creating ideas. It is an automatic process that is happening due to your past Karma (conditioning due to repeated practice).

It takes a lifetime to develop the wisdom and compassion that Buddha talked about. It cannot be understood purely using logic. You have to get the experience of a calm unbiased mind.

Even though people like her are well-intentioned but they should stop to think of the possibility that they may not understand what they are talking about as well as they think they do.
