Gross Meditation, Subtle Meditation, Very Subtle Meditation

Gross meditation is watching the mind, being mindful and aware.
Subtle meditation is awareness that the mind is still and empty of thoughts: there is, however, a me and there is awareness, so there is a duality.
Very subtle meditation is the realisation that there is nothing but awareness. There is no me. No meditator. That is non-duality.

In ordinary life, we can, of course, go the opposite way: gross mind, subtly gross mind, very gross mind.

Gross mind follows rules of do’s and don’ts, and has tantrums. 😀
Subtly gross mind is sophisticated and proud, and has superior tantrums. 😀 😀
Very gross mind is a narcissistic psychopath who has totally lost the plot and has global tantrums. 😀 😀 😀
