Water
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.
Arcana Coelestia #25
25. 'Spreading out the earth and stretching out the heavens' is a common expression in the Prophets when the subject is man's regeneration, as in Isaiah,
Thus said Jehovah, your Redeemer, He who formed you from the womb, I am Jehovah who makes all things, who stretches out the heavens Alone, and who spreads out the earth by Myself. Isaiah 44:24.
Also, when it is speaking of the Lord's Coming,
A bruised reed He does not break off and a smoking wick He does not quench; He brings forth judgement towards truth; that is, He neither shatters man's illusions nor stifles his desires. Instead He bends them towards truth and good. This verse in Isaiah continues,
The God Jehovah creates the heavens and stretches them out: He spreads out the earth and what comes from it: He gives breath 1 to the people upon it, and spirit to those who walk on it. Isaiah 42:3-5.
Such phrases recur several times elsewhere.
