Warmth is Insufficient. Attention is Necessary
"Prayer is made of attention. It is the direction towards God of all the attention that the soul is capable of. The quality of the attention makes for much of the quality of the prayer. It cannot be replaced by the heart's warmth."
I am struck by the fact that so many people feel that simply the heart's warmth is what makes for love. For Weil, love is also comprised of the intellects willed focus, the careful study. The scratching of the scholar's pen.
In order to love, one must reflect deeply, thinking, praying, and, yes, reasoning.
