Source of peace
I very much desire you to be able to acquire calm and peace. The best way to acquire this calmness is complete resignation to Gods holy Will: here is where the region of peace lies
Try hard to desire nothing, not to attach your heart to anything without having first of all presented it to God and placed it in the Sacred Heart of Jesus so as to be wanting it in Him and with Him.
One of the main reasons why we lose our peace of soul is that we desire something, we fix our hearts on some object without knowing whether God wants it or not, and so, when an obstacle opposes our desires, we worry about it, we move away from conformity to his holy Will and lose our peace.
Ecclesiasticus 32:4
