Question: Can saying to yourself that there is only the Creator protect you from disturbances, or is this only a psychological self-deception?
Answer: No, it isn’t only psychological. This is how a person is built. If you repeat the expression, “There is none else besides Him,” all of the time in every situation you encounter in life, you cannot imagine what it can teach you.
It isn’t just a mantra that you say because you have been told to say “hocus pocus,” and you repeat that.
If a person tries to connect any situation in this world with its source, if he connects the group and the Creator to himself, it constantly keeps him in the right direction and helps him to advance.
