KumariDevi (Paula) talks about how humanity helps each other to awaken. By looking into the reflection of others you gain a greater perspective of where you’re at on your own path. This is especially true if you make a comment about something in someone else. We call this gossiping. To locate what’s out of balance gossip away. Everything you find in your friends or strangers is also in you.
Why change? Because you can only experience your own level of consciousness. If you are unhappy you’ll draw in all the people are also unhappy. To change you’ll need to be happy first and then you’ll draw in those people. This goes with everything in life not only happiness.
Know thy Self, the famous statement by Jesus and Buddha is becoming self-aware.
