A beautiful poem by Ascended Master Lau Tzu 
describes why we practice meditation and what it does for our wellbeing.

“Always We Hope”
Always we hope
someone else has the answer.
some other place will be better,
some other time it will all turn out.
This is it.
no one else has the answer.
no other place will be better,
and it has already turned out.
At the center of your being
you have the answer;
you know who you are
and you know what you want.
There is no need
to run outside
for better seeing.
Nor to peer from a window.
Rather abide at the center of your being;
for the more you leave it, the less you learn.
Search your heart
and see
the way to do
is to be.
–Lao Tzu
(translated by Witter Bynner: The Way of Life, According to Lao Tzu)
