Also, in the etheric state, you have the ability to step into the subtle energy of another person. For example, in my Developing the Sixth Sense tape series. Visiting another person etherically in this way is okay, providing you're not manipulating them or making them do things they don't want to do. It's a way of being with them, concentrating on that person. Pick total strangers.
Velocity is the key.
Breathe out a short sharp breath and use the force of your will, and whack 'am hard in the heart with all the love you can muster. And as you touch them etherically with your fast-moving dollop of love, notice them blink or move their eyes suddenly. Sometimes you'll see them turn around like they're looking for where the energy came from, but they don't understand what it is they are feeling. Often you'll see them smile, and sometimes they'll start talking to themselves. It's a fun game, but it tires you out after a while so don't overdo it.
