This wallpaper comes with a very good reminder from Sai Baba of Shirdi. Sai Baba has given this sutra (a very short, yet profound line which can transform us). Sai Baba reminds us that we wrongly think we are different from one another. He (the supreme) is inside us and we are inside HIM. Then we will realize it.
If we remember that there is just one reality and everything is within one reality the thought would lead us to the realization of that supreme reality. The truth.
