I may have shared some thoughts on silence from St. Seraphim a long time ago, but one of my friends shared this with me and I thought it worth copying.
When you pray, be like the mountain
in stillness, in silence;
thoughts rooted in eternity.
Do nothing, just sit, just be;
and you will harvest the fruit of your prayer.
I suspect I did share this at an earlier date, but there are five verses and I am going to use them this week while I am recuperating from pneumonia that has really knocked all the energy out of me!
