Moving of th' earth brings harms and fears ;
Men reckon what it did, and meant ; 10
But trepidation of the spheres,
Though greater far, is innocent.
Dull sublunary lovers' love
—Whose soul is sense—cannot admit
Of absence, 'cause it doth remove 15
The thing which elemented it.
But we by a love so much refined,
That ourselves know not what it is,
Inter-assurèd of the mind,
Care less, eyes, lips and hands to miss.

athquakes cause harms and fears/has harmful consequences.

People reckon what they did and meant

On the contrary, the movement of the spheres, though it is a greater event, is harmless

Common people’s love, dependent of the senses, cannot survive separation because absence removes everything that constitutes it

On the contrary the love we share is so pure unsomuch that we ourselves can’t describe it/define it,
it is so spiritually strong and noble, that we don’t need to worry about missing (THE?) physical contact(is it better to say: sensual pleasures?) it is so spiritually strong that we don’t need to fear absence
