Shiva has been a strong merge for me typically. Feel it in a way that changes my breathing pattern, and makes me feel like I’m larger than life.
Have also experimented with others. Some with strong reactions, some not.
Though strongest impact for me happened years again before I had ever even heard of energy centers or would have considered merging with beings an option..
my brother has just passed away a few hours prior and I was in a very bad emotional place. Trying to fall asleep, I kept seeing him dying and it would shake me up again. In the middle of one of these shake up moments, I felt something enter through my crown, travel down my body and exit through my feet. Lasted a split second, if that. But was completely “wiped clean” of emotion or troubles. Laughed and fell asleep. 😊 Again was a long time ago and was shocked by it, not sure who it was, but knew it was someone/something higher than me.
