Water is the basis of life, the essential ingredient in all drinks, and in the form of rivers, lakes and oceans supports life in myriad ways. The spiritual meaning of water is similarly basic: It represents truth in general, the ideas and concepts that guide us to do good things in our lives. In a more specific sense, it represents truth at its simplest level: the ideas we learn from the Bible and simply believe. Swedenborg refers to this as “natural” truth or “truths of faith.” They are not things we have explored, figured out or confirmed through life; rather they are things that we accept to be true because we’ve been told they are true. Like water, these ideas flow to us from other sources. And like water, they are ever-changing; to build something permanent we might look to the more permanent ideas represented by stones. But water is crucial to life, and so are these accepted ideas. Water can also, of course, be threatening. Rivers, lakes and oceans are inherently dangerous, and flooding was an ever greater threat in Biblical times than it is now. These aspects represent the opposite meaning – water as falsity, twisted ideas which support evil and can overwhelm and destroy us if we’re not careful.

Air" in the Bible represents thought, but in a very general way – our capacity to perceive ideas and the way we tend to think, rather than our specific ideas about specific things. We see the world around us through the air, and seeing corresponds to understanding. We hear through the air, and hearing corresponds to being taught and obeying. Birds fly in the air, and they represent specific thoughts and ideas. And breathing itself – taking in air and passing oxygen to the blood – represents our understanding of true spiritual ideas.

In Genesis 1:26, when used with fowls or birds of the air refers to the air we breathe, but sky, or heavens where are stars, and together these terms refer to both the spiritual and natural man, and to their food, or goods and truths. (Arcana Coelestia 57, 58)

In Genesis 3:8, the only Old Testament reference to air is in the phrase "cool of the day" (at the time of the evening breeze) which signifies the period when the church still had some spiritual perception. (Arcana Coelestia 221)

In Revelation 9:2; 16:17, air signifies the divine truth, darkened by infernal falsities. (Apocalypse Explained 541, Apocalypse Revealed 423)

In Revelation 16:17, everyone in the spiritual world breathes air according to his faith. (Apocalypse Revealed 708, Apocalypse Explained 1012, Apocalypse Revealed 708)
