Question: What does it mean: “Thou shalt love thy neighbor as thyself”? What does it mean to love yourself?
Answer: To the same extent that you can egoistically imagine how to love yourself, you must also love another.
Naturally, it will be different at different levels. The more you rise with the help of your growing egoism, the more you will love yourself. And this will serve as an example of how you should love the other even more.
Question: If a person grows on the spiritual level, does he become better in everyday life and change on the physical level?
Answer: No. A person who grows spiritually is absolutely invisible in our world in his growth, in his changes. After all, this does not happen in properties that people can detect, determine, and measure.
