"I will never do anything with haste or agitation."
"This was the constant prayer of St. Teresa Margaret who in the midst of a surprising amount of activity, always maintained 'a peaceful, calm attitude, which showed her perfect self-control in each one of her actions.'"
Jesus chided Martha, not because she gave herself to activity but because she was anxious about it. God wants activity, but not anxiety, for even in necessary activity the soul should attend to the one thing necessary, that is, union with Him. Therefore as soon as a soul perceives that it is beginning to lose its interior calm, it should interrupt its work, if possible, at least for an instant, and retire into its interior with God. These brief moments of pause, frequently repeated, will accustom it, little by little, to keep calm and recollected in God, even in the most absorbing activity."
