Meditation is like a single log of wood. Insight and investigation are one end of the log; calm and concentration are the other end. If you lift up the whole log, both sides come up at once. Which is concentration and which is insight? Just this mind.
Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam.
If the traveller can find A virtuous and wise companion Let him go with him joyfully And overcome the dangers of the way. But if you cannot find Friend or master to go with you, Travel on alone.
Silence and stillness are not states and therefore cannot be produced or created. Silence is the non-state in which all states arise and subside. Silence, stillness and awareness are not states and can never be perceived in their totality as objects. Silence is itself the eternal witness without form or attributes. As you rest more profoundly as the witness, all objects take on their natural functionality, and awareness becomes free of the mind's compulsive contractions and identifications. It returns to its natural non-state of Presence.
When the mind goes beyond the thought of 'the me,' the experiencer, the observer, the thinker, then there is a possibility of a happiness that is incorruptible.
Meditation is not a process of learning how to meditate; it is the very inquiry into what is meditation. To inquire into what is meditation, the mind must free itself from what it has learnt about meditation, and the freeing of the mind from what it has learnt is the beginning of meditation.
