Every human being should essentially have three qualities - Nischalathwa, Nirmalathwa and Nirmohathwa  (Steadiness, Purity and Detachment). One who has these three qualities is verily God Himself. You need not enquire from others, whether you are good or otherwise. Your conscience  is your own judge. You should always think of God. People worship God, sing His glory, thinking that He is present in some distant place. There have been many Divine Incarnations in the past, but the inherent Divine Principle in all of them is one and the same. Your heart is really the temple of God. Hence, fill your heart with Love.  

-Divine Discourse, Prasanthi Vahini.

Develop Love, Scatter Love, Reap Love.  This is the noblest service. - Baba
