The 23rd Psalm is one of the best-known and most-loved literary works in the world, and it may well be the best poem ever written. It is also a fine example of the power of figurative language: We read deep things into the vision of ourselves as sheep, led to green pastures and good water by a kind shepherd. It’s empowering to feel the confidence to go fearlessly into the valley of the shadow of death, and to feel the love and caring of a table prepared by the Lord and a cup so full it overflows.

What people don’t know, however, is that this language actually has precise internal meanings, and that when we see them there is an even deeper beauty in the poem. That’s because what it actually describes is the path to heaven, and the fierce desire the Lord has to lead us there.

The first step is to let the Lord be our shepherd – to accept His teaching and His leadership. The green pastures and the still waters represent the things He will teach us for the journey. Then He begins working inside is, setting our spiritual lives in order, so that we desire to do what’s good and to love one another. That’s represented by restoring our souls and leading us in the paths of righteousness.

But we will still face challenges. We still live external lives, out in the world, and we are subject to desires that arise in those externals, in our bodily lives. That’s the valley of the shadow of death. But the rod and staff represent truth from the Lord on both external and internal levels, ideas that can defend us against those desires.

And if we keep following, the Lord will prepare a table for us – a place inside us that he can fill with love (the anointing oil) and wisdom (the overflowing cup). Thus transformed, we can enter heaven, with love for others (“goodness”) and love from the Lord (“mercy”) and can love and be loved to eternity.

One of many beautiful things about this is the fact that it is the Lord who really does all the work. In the whole text, the only action taken by the sheep is walking through the valley of the shadow of death. Other than that, they follow the Lord, trust the Lord, accept the blessings of the Lord. And that is really true! In external states (in the valley) we might seem to be doing the work ourselves, but internally, spiritually, we simply need to give ourselves to the Lord and let Him bless us.

The underlying idea here is that the Lord created us so that He could love us, in loving us wants us to be happy, knows that our greatest happiness will come from being conjoined to Him in heaven, and Himself wants nothing more than to be conjoined to us. So everything He does, in every moment of every day for every person on the face of the planet, is centered on the goal of getting that person to heaven. He wants each and every one of us in heaven more than we are capable of imagining. We just need to cooperate.

10208. 'And Aaron shall make expiation on its horns' means purification from evils by means of the truths of faith which spring from the good of love. This is clear from the meaning of 'making expiation' as purifying from evils, dealt with in 9506; from the representation of 'Aaron' as the Lord in respect of Divine Good, and in respect of the work of salvation, dealt with in 9806, 9946, 10017; and from the meaning of 'horns' as powers, dealt with in 10182, and also outer levels, 10186. The reason why purification by means of the truths of faith which spring from the good of love is meant is that expiation was made by means of blood, and 'blood' means the truth of faith emanating from the good of love, 4735, 7317, 7326, 7846, 7850, 7877, 9127, 9393, 10026, 10033, 10047; and all purification from evils is accomplished by means of the truths of faith that spring from the good of love, 2799, 5954(end), 7044, 7918, 9088. The fact that expiations were made by the blood on the horns of the altar of burnt offering and the altar of incense is clear in Leviticus 4:3, 7, 18, 25, 30, 34; 16:18.

[2] The altars were expiated in this way because holy things were polluted by the sins of the people. The people represented the Church; therefore those places which were the Church's, called its sanctuaries, such as the altar and the tent, together with their contents, were defiled whenever those people were guilty of sin; for those sanctuaries were places belonging to the Church. This is also made clear in Moses,

You shall separate the children of Israel from their uncleanness, in order that they may not die in their uncleanness when they pollute My dwelling-place which is in their midst. Leviticus 15:31.

And in another place,

Aaron shall expiate the holy place from the uncleanness of the children of Israel. Thus shall he expiate the holy sanctuary, and the tent of meeting, and the altar. Leviticus 16:16, 33.

[3] The implications of all this are that those things which are called the holy things of the Church are not holy unless they are received with holy respect; for unless they are received with that respect what is Divine does not flow into them. Anything holy that exists with people is holy only by virtue of what is Divine flowing into it; sacred shrines for example, the altars there, and the bread and wine for the Holy Supper are made holy solely by the presence of the Lord. Therefore if the Lord is unable to be present there on account of the people's sins, those things have no holiness because they lack what is Divine. Furthermore the holy things of the Church are rendered unholy by sins because sins take what is Divine away from them.

[4] This then is the reason why sanctuaries are said to have been polluted by the uncleanness of the people and why those places therefore had to be expiated annually. The reason why the expiations were made with blood on the horns of the altars and not on the altars themselves was that the horns were the extremities of them, and nothing of a person has been purified unless the extremities or what is outermost has been purified. For inner things flow into those that are outermost, but the state of the outermost conditions the inflow. Consequently if what is outermost has been perverted the things within become perverted; for when those inner things flow into outermost ones, the recipient forms into which they descend are conditioned by the state in which the outermost things exist. The situation is like that when the eye is in bad condition; the power of sight which comes from within sees things only as that eye-condition will allow. Or it is like that when the arms are in bad shape; the powers which come from within exert themselves only as that condition will allow. Consequently if the natural man has been perverted the spiritual lacks the opportunity to function properly within the natural man, and this is why the spiritual or internal man is closed.

[5] But see what has been shown already on these matters, namely the following;

If a person is to be purified the natural or external man must be purified, see the places referred to in 9325(end).

This is because the path that all influx takes is from the internal to the external, and not vice versa, 5119, 6322.

For it is on the natural level within a person that influx from the spiritual world reaches its destination, 5651.

The outward aspects of a person have been formed to serve the inward, 5947, 9216, 9828.

Thus the external man must be altogether subject to the internal, 5786, 6275, 6284, 6299.

This is because the internal man is in heaven and the external man is in the world, 3167, 10156.

And the external man by himself or left to himself alone acts contrary to the internal, 3913, 3928.

In addition to all this, see 9701-9709 stating what the internal man is and what the external man is.
