The word is: LOVE
The meaning of life is: The meaning of life is continuous learning, even in death and beyond.
What is reality: Love is the only existing reality. From love everything is created to love all returns.
What is time: Time is a construct, a prison. Every living thing has its own "time." Importantly, there is no universal time.
Is there free will: Yes and no. Before we were born (existence) we have to choose the free will, what experience we want to do, what kind of life we want to live. After we are born, we have our "choice" fulfill, that elected life to live. Example: "In the beginning God said, Let there be light (free will), and there was light (fulfillment of the free will of God)."
Save the world or not? Remember, you save the world for all, even for the evil creatures. :)
