Cittanupassana: This exercise aims to perceive and understand any stages of the mind. The sutta says:"And how does a monk remain focused on the mind in and of itself? There is the case where a monk, when the mind has passion, discerns that the mind has passion. When the mind is without passion, he discerns that the mind is without passion. When the mind has aversion, he discerns that the mind has aversion. When the mind is without aversion, he discerns that the mind is without aversion. When the mind has delusion, he discerns that the mind has delusion. When the mind is without delusion, he discerns that the mind is without delusion.
"When the mind is restricted, he discerns that the mind is restricted. When the mind is scattered, he discerns that the mind is scattered. When the mind is enlarged, he discerns that the mind is enlarged. When the mind is not enlarged, he discerns that the mind is not enlarged. When the mind is surpassed, he discerns that the mind is surpassed. When the mind is unsurpassed, he discerns that the mind is unsurpassed. When the mind is concentrated, he discerns that the mind is concentrated. When the mind is not concentrated, he discerns that the mind is not concentrated. When the mind is released, he discerns that the mind is released. When the mind is not released, he discerns that the mind is not released.
"In this way he remains focused internally on the mind in and of itself, or externally on the mind in and of itself, or both internally and externally on the mind in and of itself. Or he remains focused on the phenomenon of origination with regard to the mind, on the phenomenon of passing away with regard to the mind, or on the phenomenon of origination and passing away with regard to the mind. Or his mindfulness that 'There is a mind' is maintained to the extent of knowledge and remembrance. And he remains independent, unsustained by (not clinging to) anything in the world. This is how a monk remains focused on the mind in and of itself.
