Be still and cool

Reading today I came across this written by George Fox (the founder of the Quaker movement) in 1658.  It still  has application some 363 years later, reckon it always will:

“Be still and cool in Thy own mind and spirit, from thy own thoughts, and then thou wilt feel the principle of God to turn thy mind to the Lord God, whereby thou wilt receive God’s strength and power from whence life comes, to allay all blusterings, storms, and tempests.”
