How do spirit-lives impress their thoughts?

Spirit-lives do not speak another language from those of earth that is not another added to, yet different from those, as Hebrew is another language differing from English.

Spiritual language is a universal, primeval instinct (so-to-speak). 

Spirit-lives impress their thoughts on one another by―and through―will power―and their language is limited, not by words, but by their own power of feeling, and by the hearer’s power of sympathy. 

This language is only the perfection of those powers, which are in every human being, though nearly dormant, and which have been weakened through long ages of disuse, and by a more artificial speech. 

There are many things, such as the universal needs of the body, or the simple passions, which can be expressed and understood by all independently of mere words. 

Joy, fear, grief, hunger, love need no words, and can be expressed by and through the eye. 

Even the outward is not always necessary, for one can influence and control the thoughts and feelings of others even without the bodily presence. 

So spirit-lives impress their thoughts on others, first in a weak and broken manner, like a child learning to talk, and then more and more fully as the soul expands―also, as spirit-lives gain more experience in their new life, their vocabulary increases. 

Then, with regard to others’ powers of understanding them, this, too, does not depend on any artificial acquirement of mere words, nor yet on what would answer to the power of the intellect, but the power of comprehension equals the power of sympathy, that is, the capability of feeling as the speaker does were you in his circumstances.

Again, this is only the natural human method enlarged and rectified, for the knowledge of words alone does not enable one to enter into the heart and mind of the speaker.

Linnaeus kneeling before the glorious works of God, with hands folded and eyes upraised in worship, would be to some a true child of nature, acting in the most natural and simple manner—to another, he might be only a fool or a drunkard. 

“These men are filled with new wine,” some say, while others—“we do hear in our own language the wonderful works of God,” and yet again to others it might be merely “a pleasant sound as of one playing on an instrument.”

Still, spirit-lives are not without that joy, which arises from musical sounds―only such sounds are not caused by vibrations of the atmosphere, but by vibrations of the soul-currents, which are heard inwardly by those whose souls are attuned to the same key.
