Clarity of Insight¹

A further aspect of mental development that leads to clearer and deeper insight is meditating on an object to calm the mind down. The calm mind is the mind that is firm and stable in samādhi (concentration). This can be khanika samādhi (momentary concentration), upacāra samādhi (neighbourhood concentration) or appanā samādhi (absorption). The level of concentration is determined by the refinement of consciousness from moment to moment as you train the mind to maintain awareness on a meditation object.

In khanika samādhi (momentary concentration) the mind unifies for just a short space of time. It calms down in samādhi, but having gathered together momentarily, immediately withdraws from that peaceful state. As concentration becomes more refined in the course of meditation, many similar characteristics of the tranquil mind are experienced at each level, so each one is described as a level of samādhi, whether it is khanika, upacāra or appanā. At each level the mind is calm, but the depth of the samādhi varies and the nature of the peaceful mental state experienced differs. On one level the mind is still subject to movement and can wander, but moves around within the confines of the concentrated state. It doesn't get caught into activity that leads to agitation and distraction. Your awareness might follow a wholesome mental object for a while, before returning to settle down at a point of stillness where it remains for a period.

You could compare the experience of khanika samādhi with a physical activity like taking a walk somewhere: you might walk for a period before stopping for a rest, and having rested start walking again until it's time to stop for another rest. Even though you interrupt the journey periodically to stop walking and take rests, each time remaining completely still, it is only ever a temporary stillness of the body. After a short space of time you have to start moving again to continue the journey. This is what happens within the mind as it experiences such a level of concentration.

If you practise meditation focusing on an object to calm the mind and reach a level of calm where the mind is firm in samādhi, but there is still some mental movement occurring, that is known as upacāra samādhi. In upacāra samādhi the mind can still move around. This movement takes place within certain limits, the mind doesn't move beyond them. The boundaries within which the mind can move are determined by the firmness and stability of concentration. The experience is as if you alternate between a state of calm and a certain amount of mental activity. The mind is calm some of the time and active for the rest. Within that activity there is still a certain level of calm and concentration that persists, but the mind is not completely still or immovable. It is still thinking a little and wandering about. It's like you are wandering around inside your own home. You wander around within the limits of your concentration, without losing awareness and moving outdoors, away from the meditation object. The movement of the mind stays within the bounds of wholesome (kusala) mental states. It doesn't get caught into any mental proliferation based on unwholesome (akusala) mental states. Any thinking remains wholesome. Once the mind is calm, it necessarily experiences wholesome mental states from moment to moment. During the time it is concentrated the mind only experiences wholesome mental states and periodically settles down to become completely still and one-pointed on its object.

So the mind still experiences some movement, circling around its object. It can still wander. It might wander around within the confines set by the level of concentration, but no real harm arises from this movement because the mind is calm in samādhi. This is how the development of the mind proceeds in the course of practice.

In appanā samādhi the mind calms down and is stilled to a level where it is at its most subtle and skilful. Even if you experience sense impingement from the outside, such as sounds and physical sensations, it remains external and is unable to disturb the mind. You might hear a sound, but it won't distract your concentration. There is the hearing of the sound, but the experience is as if you don't hear anything. There is awareness of the impingement but it's as if you are not aware. This is because you let go. The mind lets go automatically. Concentration is so deep and firm that you let go of attachment to sense impingement quite naturally. The mind can absorb into this state for long periods. Having stayed inside for an appropriate amount of time, it then withdraws. Sometimes, as you withdraw from such a deep level of concentration, a mental image of some aspect of your own body can appear. It might be a mental image displaying an aspect of the unattractive nature of your body that arises into consciousness. As the mind withdraws from the refined state, the image of the body appears to emerge and expand from within the mind. Any aspect of the body could come up as a mental image and fill up the mind's eye at that point.

Images that come up in this way are extremely clear and unmistakable. You have to have genuinely experienced very deep tranquility for them to arise. You see them absolutely clearly, even though your eyes are closed. If you open your eyes you can't see them, but with eyes shut and the mind absorbed in samādhi, you can see such images as clearly as if viewing the object with eyes wide open. You can even experience a whole train of consciousness where from moment to moment the mind's awareness is fixed on images expressing the unattractive nature of the body. The appearance of such images in a calm mind can become the basis for insight into the impermanent nature of the body, as well as into its unattractive, unclean and unpleasant nature, or into the complete lack of any real self or essence within it.
