Yessss... opening the heart will remove a lots of dark sticky stuffs and worth it, if you ask me...it did wonders for myself.
Samadhi the Highest State of Consciousness and Bliss...(so glad for google)
I did contact my HigherSelf/Ish/Disk whatever name you want/wish to call it..a few time, and most experiences were worth the effort cause i did not want to come back, just wanted to last forever a longing for home.
I've posted the experience here somewhere last year or 2 yrs ago...should be there still.
As for the 3rd sometimes strobing as you put it...mine feel like ..what i call..Butterfly Effect.. i'm not a butterfly but if i was i could imagine how it will feel like flapping both my wings in unison...faster and faster with each flaps....the feeling i get when activated... flapping/moving/vibrations going deeper and deeper...feels good actually.
