Understanding Mindfulness in the Mind : หน้า 130/263

mind in the mind, it means mindfulness only of the sphere of central processing — and not the spheres of the mind involved with perception, sensory registration or cognition. It is no use having mindfulness of any other parts of the mental process — because the layers of the mind cannot exchange roles any more than the moon can exchange its role with the sun. The pure mind [bhavaṅgacitta] has the character of a clear, translucent sphere about the size of the pupil of our eye. However when the mind is tainted with desire which is red in colour, then the mind will become coloured red and will lose its translucence. If it is tainted with illwill which is dark greenish in colour then the mind will become darkened and muddy. The mind is of the nature of arising and extinguishing the whole of the time — this is how the mind changes. So how can we manage continually to cultivate mindfulness of the mind both inside and outside? Cultivating mindfulness of the outer mind is to see the mind of the physical human body. Cultivating mindfulness of the inner mind is to see the mind of the subtle human body and how it changes at any moment — how it arises and extinguishes, arises and extinguishes. Once the meditator is able to observe as described, knowing with clear comprehension the state of the inner mind, he should know it according to reality and feeling of the arising and extinguishing without letting craving [tanhā] or views [diṭṭhi] affect how he sees, without attachment to the things of the world, knowing one has no further attachment for the things of the world — this is how we can continuously cultivate mindfulness of the mind in the mind both inside and outside. 128
