With reference to the following passage from Act 3, Scene 2:
"How all the other passions fleet to air,
As doubtful thoughts, and rash-embraced despair,
And shuddering fear, and green-eyed jealousy!
O love, be moderate. Allay thy ecstasy.
In measure rein thy joy. Scant this excess.
I feel too much thy blessing. Make it less,
For fear I surfeit."
After Bassanio finally chooses the correct box, Portia describes her true feelings of love for Bassanio to the audience. She reveals the excitement of new love and appears to be in a state of extreme joy and happiness. She describes the way in which her feelings of love overpower negative feelings, such as jealousy or fear. She also recognises the extent to which these feelings of love can seem overwhelming. Despite not knowing each other very well, Portia’s expressions serve as proof that love can come quickly and unexpectedly.
Perhaps you could examine the notion of love coming quickly and unexpectedly using your knowledge and understanding of the Merchant of Venice and assess its relevance in an effort to establish some sort of point.
I hope this helps!
