A -> B

You: "What makes you think it's possible to think of two opposites as the same thing?"

Him: "If you reach sort of a "superhuman" mind you can. If reality has 1 essense, from the aspect of that essense, there's no such thing as "opposite". Every coin has 2 sides. For example, when you're feeling good from something, you also feel bad meanwhile because you're afraid to lose what makes you feel good. If you keep trying to see the 2 sides of anything, you can reach this superhuman mind"

What to answer?

a. 'Why trying to see two opposites as the same thing would lead me to seeing this 1 essense?"

b. "Can you show me as aspect from which nothing actually exists, and another aspect from which everything exists?"
