We are talking about the complete and absolute aim only toward the Creator. Do not associate Him in any way with any other actions. Not in any way!
On the contrary, all actions, thoughts, qualities, and intentions should be directed toward Him! No matter what they are.
“In vain” means: do not take Him apart in parts for your life. Direct everything only at Him and at His level. Then as a result of your work, you will see how much this world was created in order to elevate you to the Creator.
Comment: In fact, this phrase sounds like a superstition.
Answer: No! “You shall not take the name of the Creator in vain” means: do not pull Him for yourself over small things. On the contrary, bring all the little things in life to Him.
A person should align all his actions, thoughts, feelings, aspirations, and plans with the fact that there is one Creator, the one and only, and we must come to Him.
