Their inactivity seems idleness to them, and they mistake the restless impulse which bids them be up and doing for the voice of conscience or the inspiration of heavenly wisdom; but it is neither.
Sometimes it is a superfluity of natural energy seeking an outlet; sometimes it is the result of the strain placed upon nature by a very powerful influx of grace.

The infusion of power from above is often greatly in excess of the light necessary for guidance in its use.
This last rarely comes entirely from the inner touch of the Holy Spirit.

In the lives of the Fathers of the Desert we read of a certain young brother, Ptolemy, who went astray from sound spirituality.

When admonished he asserted that he need learn the spiritual life from none save the Holy Ghost, of whose inspirations any man of good will could be certain.

He was told by the old monks that the inspiration of the Holy Ghost and the understanding of the same are two distinct things, and that this understanding is disclosed only to him whose will has been purified by the practice of obedience and humility.
