10050. 'And its legs' means purification of the more external things belonging to the natural man. This is clear from the meaning of 'washing the legs' as purification of the natural man (for the meaning of 'washing' as purifying, see immediately above in 10049); and from the meaning of 'the legs' as the more external things belonging to the natural man. The reason why these things are meant by 'the legs' is that one must at the same time understand the feet, since an animal's four legs are closely connected to its feet, and 'the feet' by virtue of their correspondence mean the natural or external level in a person, see 2162, 3147, 3761, 4938-4952.

[2] Much the same is meant by 'the legs' in Amos,

As the shepherd rescues from the mouth of the lion two legs or a piece of an ear, so will the children of Israel dwelling in Samaria be rescued, on the corner of a bed and on the end of a couch. Amos 3:12.

'The lion' here means those who lay the Church waste, 'legs' the external part of it, which is also the external part of the natural man, 'a piece of an ear' its discernment, and those 'dwelling in Samaria' those whose worship is external. 'The corner of a bed and the end of a couch' is the lowest part of the natural, which is external sensory awareness and its truth and good.

[3] In Daniel's description of Nebuchadnezzar's statue - its head made of pure gold, breast and arms of silver, belly and side of bronze, legs of iron, and feet partly of iron and partly of clay, Daniel 2:32-33 - what is meant by 'the legs' is the truth of faith in the external or natural man; and the same thing is also meant by 'iron', see 10030. The reason why the legs in the description are distinguished from the feet is that human legs are by nature different from animal legs.

3213. REPRESENTATIONS AND CORRESPONDENCES - continued

In the world of spirits countless representatives manifest themselves almost constantly. They are visible forms of spiritual and celestial things, not unlike the forms that occur in the world. The origin of them I have been given to know through daily association with spirits and angels. Representatives in the world of spirits flow in from heaven, and from the ideas and the discussions of the angels there. Indeed when angels' ideas and their discussions resulting from those ideas come down to spirits, they present themselves in a variety of ways as representatives. Upright spirits are able to know from those representatives what angels are discussing with one another, for inwardly representatives have within them that which comes from angels, and since this stirs the affections of those spirits, it is perceived even as to the essential nature of it. Angels' ideas and discussions cannot present themselves to spirits in any other way, for an idea existing with an angel contains immeasurably more than an idea existing with a spirit, and unless it were given visible form and presented itself in a representative way, and so visually by means of images, a spirit would understand hardly anything whatever of those things. For such things are for the most part inconceivable. But when they are represented by means of visible forms they are rendered such that spirits are able to comprehend some fairly general aspects. This is a marvel, for not even the smallest detail of the things that are represented fails to express something spiritual or celestial present in an idea existing with the angelic community from which the representative flows down.
