The truth must be found. What is this truth? The truth is about you, what you are, who you are, why you are here, etc. You must find an answer to this in your lifetime. What else do you have to do? Inquire into the nature of existence and find a philosophy that works for you. How do you know it works for you? Because you feel happy, satisfied and at peace with the world.
As long as you are not satisfied with your answers to life’s questions, keep on seeking, searching, questioning, and experiencing. This truth can be vastly different from the truth of your parents, your teachers, or even the people around you. It is your own truth that matters.
Selfishness or hurting others in their pursuit towards happiness cannot be included in your truth. That much is certain. Being insensitive towards the needs of others is unacceptable. Mocking others, making fun of others also shows lack of good sense. The truth is mostly found within yourself, and then it is reflected in the outside world in which you exist. Speak as you think and act as you speak.
