You can not let someone else except yourself understand something.
Actually it’s literally yourself who you see in outside in a certain dimension. It’s not about psychological projection. In that dimension, no one can see someone else. Literally we are connected and influence at elementary particle level each other all the time.
If you want the world of happiness, you should understand this…
If you can be happy every moment with every side of yourself, it’s that you are automatically creating your field of happiness as well which will influence other’s fields absolutely.
It’s you can create the world of happiness.
You are a creator of your world.
