588. Which can neither see nor hear nor walk, signifies in which and from which there is nothing of the understanding of truth or the perception of good, and thus nothing of spiritual life. This is evident from the signification of "to see," as being to understand truth (See above, n. 11, 260, 529); also from the signification of "to hear," as being to perceive and obey (See also above, n. 14, 249), and as being to have understanding to perceive, n. 529; also from the signification of "to walk," as being to live spiritually, and in reference to the Lord that it is life itself (See above, n. 97). From this it is clear that "not to see, to hear, or to walk," signifies that there is no understanding of truth, no perception of good, and thence no spiritual life; these are not in idols or from them, for "idols" signify the falsities of doctrine, of religion, and of worship, and such things are not in falsities, but in truths that are from good; in truths and from them is all understanding, all perception from the will of good, and consequently spiritual life. It is said "consequently," because spiritual life consists in the understanding of truth and in perception from the will of good; for truths are in the light of heaven, and this so much that the truths themselves give light in heaven, and this because the Divine truth proceeding from the Lord makes all light in the spiritual world, and that light gives all intelligence and wisdom to angels.

Now as truths themselves are of the light it follows that falsities are of no light, for they extinguish light, consequently falsities are called in the Word "darkness" (See above, n. 526); and as they are darkness, they are the shadow of spiritual death. But it is to be known that the falsities of evil constitute such darkness, not falsities that are not from evil. "To hear" signifies perception from the will of good, and thence obedience, because speech enters the ear at the same time with the sound, and the truths uttered enter the understanding and thence the thought, while sounds enter the will and thence the affection. That in the spiritual world sounds present and produce the affection which is of the will, and the words of the sound the thought which is of the understanding, may be seen in the work on Heaven and Hell 236, 241, and above n. 323. From this it can be seen why "to hear" and "to hearken" also signify to obey, and the "ear" and "hearing" obedience.

529. Verse 13. And I saw, and I heard one angel flying in midheaven, signifies the Lord enlightening all in the heavens respecting the state of the church at its end. This is evident from the signification of "to see and to hear," as being to open the understanding to perceive (of which presently); and from the signification of "angel," as being the Lord. That "angels" in the Word mean Divine truth proceeding from the Lord, thus the Lord Himself in relation to Divine truth, may be seen above (n. 130, 200, 302), here the Lord manifesting what the church is to be in the last times in respect to the reception of Divine truth. Also from the signification of "to fly," as being to enlighten and give understanding (of which presently); also from the signification of "in midheaven," as being in the whole heaven, or all who are in the heavens (that "in the midst" signifies in the whole and thus all, see above, n. 213). From this it can be seen that "I saw, and I heard one angel flying in mid-heaven," signifies the enlightenment of all who are in the heavens respecting the state of the church at its end. Enlightenment respecting the state of the church at its end is meant, because this is what is treated of in what follows. "To see and to hear" signifies to open the understanding to perceive, because "to see" signifies to understand, and "to hear" to perceive (that "to see" signifies to understand, see above, n. 260; and that "to hear" signifies to perceive, also above n. 14, 108).

[2] "To fly" signifies, in reference to the Lord, to enlighten, because "to fly" is said of the understanding, and of the extension of its vision round about, therefore in reference to the Lord, "to fly" signifies the enlightenment of the understanding. That in reference to the Lord, "to fly" signifies omnipresence, may be seen above (n. 282); consequently it signifies also enlightenment, for where the Lord is present there is enlightenment. "To fly" has the same signification in David:

God rode upon a cherub, He did fly, and was borne upon the wings of the wind (Psalms 18:10; 2 Samuel 22:11).

A "cherub" signifies the inmost heaven, "to ride" signifies to give understanding and to enlighten; "to fly" and "to be borne upon the wings of the wind" have a like meaning; but "to ride" here signifies to give understanding to and to enlighten here the inmost heaven, which is signified by a "cherub;" "to fly" also signifies to give understanding to and to enlighten the middle heaven; while "to be borne upon the wings of the wind" signifies to give understanding to and to enlighten the ultimate heaven. (That "to ride" signifies to give understanding, see above, n. 355, 364; and that a "cherub," signifies the inmost heaven, n. 313, 322, 362, 462.) "To fly" signifies to enlighten the middle heaven, because that heaven is the spiritual heaven, and spiritual things in the Word are signified by various birds, and by their wings and flights. "To be borne upon the wings of the wind" signifies to enlighten the ultimate heaven, because "wings" are for flight, and here signify enlightenment, and "wind" signifies the spiritual of that heaven; thus all this describes the omnipresence of the Lord in the heavens, thence also the enlightenment of the understanding; for as was said above, where the Lord is present there is enlightenment.
