So much truth to all of that!
I have to be careful not to look for any length of time at the animal I am trying to take. They CAN feel my predatory presence. I once had a cow elk act like she had just been slapped when I looked too long at her. I was fairly close, maybe 30-40 yards in heavy timber. I was not moving, had the wind, had not crossed the area yet, and was not in sunlight, yet she suddenly spooked. We do absolutely have an energy field, and some humans are still attuned, but I think all critters are.
But then I have had other times when interactions were very different because of signals I was intentionally sending out. Like on that sheep hunt, there was a large herd of cows and calves living up there with us. They were understandably wary of us, but I had a magical experience with them one evening. I was headed to camp, and too tired to be interested in climbing around the herd in the meadow I needed to cross. I first encountered a cow and calf at about 15 yards at the edge of timber, and sort of turned away and sent the message I wasn't interested in them and transmitted as non-predatory vibes as I could. They edged away but did not run. I think that set the stage. I then slowly walked out into the meadow, looking around at the ground, off in the distance, anywhere but directly at an elk, all the while trying to send a non-predatory vibe out. The herd simply parted and let me walk through the middle of them. None spooked. They just closed back together behind me and resumed feeding. I will never get over that.
