Drink to me only with thine eyes,
And I will pledge with mine;
Or leave a kiss but in the cup,
And I'll not look for wine.
The thirst that from the soul doth rise
Doth ask a drink divine;
But might I of Jove's nectar sup,
I would not change for thine.
I sent thee late a rosy wreath,
His thirst is a spiritual one; he seeks not liquid but the ‘divine’ drink that derives from the soul; in other words ‘love’. Interestingly, there is no hint in this stanza of a sexual attraction.  The noun ‘soul’ and the adjective ‘divine’ place his emotions on a level beyond that of the corporeal.
