* True love is not jealous. Hermia and Demetrius are both jealous of each other, and this jealousy leads to conflict and tension. However, Helena and Lysander are not jealous of each other, and their love is stronger and more enduring. This teaches us that true love is not possessive or controlling, but is instead characterized by trust and respect.
* Love can overcome obstacles. Hermia and Lysander are determined to be together, even though their parents oppose their relationship. They overcome many obstacles to be together, including a love potion, a jealous rival, and a forest full of fairies. This teaches us that true love is strong enough to overcome any obstacles.
* Deceit and trickery can have unintended consequences. Puck's mischievous use of the love potion causes confusion and chaos among the lovers. This teaches us that deception and trickery can have negative consequences, even if they are meant to be harmless.
* Dreams are powerful and can reveal our true desires. The play's title, "A Midsummer Night's Dream," suggests that the events of the play take place in a dream world. This dream world is a place where characters can express their true feelings and desires, without the constraints of reality. This teaches us that dreams can be a powerful force in our lives, and that they can help us to understand ourselves better.
