Before there is action, there is inaction. Stillness. Silence.
The practice of meditation takes one to that silence before action. As one practices meditation over time, s/he may become more accustomed to, and grounded in, that silence, so that the agitation of the world has a diminished effect upon him/her.
Sitting for meditation is like climbing into one’s own private submarine. The submarine dives under the waves and agitation of the surface into the calm water below. The more one meditates, and the more regularly, the easier it becomes for them to dive into that calm and to remain there longer. Storms do come, and the meditation submarine helps ride them out.
In addition, meditation practice helps make the mind whole. When the mind is agitated, it appears to fragment into conflicting pieces. Yet, just beneath the surface of this chaos is peace. Meditation returns one to that peace, and to unfragmented wholeness.
As the great Himalayan sage Swami Rama said, “Meditation is a dire necessity.”
