Can anyone help on that second verse?

Now, you all know what I’m speaking of when I mention you-know-what,
And I fear it’s very dangerous to even mention that.
For the other ones are (other earth is??) always near, although you may not see,
And if anyone asks who told you that, please don’t mention me. CHORUS.

I know it can't be "the other earth is," but that's what I hear.
