I have done it without being in hard jhana, but that was during the A&P so it was probably very light second jhana. I couldn’t do it with any person, but with two people close to me who seemed to be on the same frequency as me or however it works. I just thought the word ”give” and they would shake visibly from joy. They never knew in advance. That was probably very irresponsible of me to do that without asking consent. I had no idea what I was doing (this was several years ago). Thankfully, they didn’t mind (quite the contrary).

That's a beautiful  thing to do. Unless they where occupied with something important. I cant figure out the whole AP thing.im thinking of doing a short  mindfulness sitting every day on top of my 1 hour concentration  sitting. Dont really know where to start with vipasana

That's interesting. At the sangha I sometimes attend, during one particular meditation session I sat next to a guy who seemed to have whistling nostrils. Unfortunately, his nostrils were his primary meditation object. I watched my developing frustration like so: form, feeling, perception, intention and consciousness and thus resolved to ferret out that frustration with a diligence one could only attribute to the great Sariputra. I never ferreted out that frustration and instead chose to contemplate the wind element. 

I realize the following is not exactly what you are asking but it is related and folks might be interested....

I practice soft jhanas and I use the skill to try to maintain a "pleasant relaxed state" even when I am not meditating. I wrote about how this affects other people on my blog:

Apparently this is verified by scientific research:

I was going through a review phase and could call up a&p at Will in seconds and I was standing next to a friend and called it up and he said he felt the bliss in transference.
