Worry is the opposite of faith. It is the worship of the forces of nature, the power of illness, the dynamics of the market, the belief that these and mortal beings are the masters of your life.

Faith is the inner knowledge that there is really nothing else but His abundant love. It is the conviction that you have only one Master, and His love to you knows no bounds.

And that if you cannot see this love, it is because it is such awesome love, it flows to you in ways far beyond your comprehension.

If so, when His caress seems harsh, embrace it with joy. When His kisses pour down in a torrent beyond your capacity to endure, open wide.

Perhaps He is carrying you higher, closer, far beyond your tiny cell into a vast palace of blinding light. Because He desires your closeness.

Perhaps He is cleansing your body and soul, your universe and all it contains, finely tuning them to resonate with His infinite presence.

Open your heart, your mind, your soul, and all entry to His Infinite Light.

The relentless forces of nature, the pain of the body, the vicissitudes of the market, the angry power of human beings—your eyes will open and they will dissipate into oblivion. For they are nothing more than channels of endless love from an infinite G‑d.

This is happiness: Life with Him alone.

Tanya, chapter 26. Igeret HaKodesh 11.
