Several people have commented on the difficultness of this form of prayer...they have also commented on the power of it.  Yes, it's a challenge, but it so worth it to know God in the silence.

Psalm 46
God is our refuge and strength, a very present help in trouble.
²Therefore we will not fear, though the earth should change, though the mountains shake in the heart of the sea;
³though its waters roar and foam, though the mountains tremble with its tumult. Selah
⁴There is a river whose streams make glad the city of God, the holy habitation of the Most High.
⁵God is in the midst of the city; it shall not be moved; God will help it when the morning dawns.
⁶The nations are in an uproar, the kingdoms totter; he utters his voice, the earth melts.
⁷The Lord of hosts is with us; the God of Jacob is our refuge. Selah
⁸Come, behold the works of the Lord; see what desolations he has brought on the earth.
⁹He makes wars cease to the end of the earth; he breaks the bow, and shatters the spear; he burns the shields with fire.
¹⁰“Be still, and know that I am God! I am exalted among the nations, I am exalted in the earth.”
¹¹The Lord of hosts is with us; the God of Jacob is our refuge.

Take 20-30 minutes and sit in the silence.  Clear your mind and relax.  Be fully in the moment.  "Be still, and know that I am God!"
