In meditation, we try to let go of all the many mental distractions,
preoccupations, and the fleeting thoughts and associations of our
normal waking experience.
We do this, not by trying to make the mind empty, which is
impossible, but instead, by allowing the mind to focus on one subtle
element or object, which leads the attention further inward.
By giving the mind one internal focus of attention, we help the mind
to cease its other stressful mental processes, such as worry,
planning, thinking, and reasoning.
