“The true beginning of prayer is warmth of the heart, which scorches the passions and fills the soul with joy and gladness, strengthening the heart with an unshakable love and a firm assurance that leaves no room for doubt. The Fathers say that whatever enters the soul, whether visible or invisible, is not from God so long as the heart is in doubt about it and so does not accept it…”
(St Gregory of Sinai)
