Meditation is like the cloak of the good thief. You find a corner or somewhere where you can actually entertain your own self and your own soul, and understand what your work [is] here.
An interval of meditation, serious and grateful, was the best corrective of everything dangerous in such a high-wrought felicity; and she went to her room, and grew steadfast and fearless in the thankfulness of her enjoyment.
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.
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.
Proper effort is not the effort to make something particular happen. It is the effort to be aware and awake each moment, the effort to overcome laziness and merit, the effort to make each activity of our day meditation.
