In English
Whenever you come across a stranger you ask him, “Who are you?” and waste your time. Instead, question yourself, “Who am I?” By finding out the answer to this question you will be able to very easily find out who he is, since the true nature of every human being is one and the same. Every human being refers to himself as “I”. The word “I” is applicable to every individual. If you understand this one word “I”, you can understand the real nature of every being in the world.
