It should be observed that perfect love of God consists not in those delights, tears and sentiments of devotion that we generally seek, but in a strong determination and keen desire to please God in all things, and to promote His glory.
Keep this in mind, for it is very important advice, so do not neglect it until you find you have such a fixed determination not to offend the Lord that you would rather lose a thousand lives and be persecuted by the whole world, than commit one mortal sin, and until you are most careful not to commit venial sins.
His Majesty knows best what is suitable for us. There's no need for us to be advising Him about what He should give us, for He can rightly tell us that we don't know what we're asking for (cf. Mt. 20:22). The whole aim of any person who is beginning prayer ? and don't forget this, because it's very important ? should be that he work and prepare himself with determination and every possible effort to bring his will into conformity with God's will.
