Question: How is it possible to unite the whole world if nations, countries, and religions are so different from each other in every way?
Answer: These are egoistic differences. When we unite spiritually they disappear and we all become as one man with one heart.
The earthly differences actually don’t separate us at all. One person likes to spice up his food with pepper and another one doesn’t. One person holds ceremonies this way and another person that way. This doesn’t make us different at all. On the contrary, that is exactly when we begin respecting one another.
Being dissimilar does not obstruct us from coming together spiritually. On the contrary, by uniting above our egoistic differences, we make them even more powerful and all of that power is aimed at spiritual unity.
