John Of The Cross

The divine awakening produces in the soul of the perfect a flame of love which is a participate of that living flame which is the Holy Spirit Himself…this is the operation of the Holy Spirit in the soul that is transformed in love, that His interior actions cause it to send out flames…This flame wounds the soul as it is given, but the wound is tender, and, instead of causing death, it increases life; for the soul is holiest that is most wounded by love.
