I listened for nearly two hours to this. It is, as you say, pure New Age pantheism. It was a mishmash of Kabbalism, Buddhism, earth-worship, evolution, Indian shamanism, and goodness knows what. Was some of the science valid? For sure. I have heard a lot about silver compounds being used for healing and I think there may be something in that. Could 528 Hz be a healing frequency? Perhaps, on a physical and psychic level. If it is, why not just bombard silver oxide solution with a machine generating that frequency, drink it, and test it. We certainly don't need all the pagan gubbins which may actually end up giving people a false light mediated by demons. What you have is a brilliant good cop/bad cop setup, making the scientists and profiteer bad guys and the New Agers the goodies.

I actually investigated Oxysilver website a few years ago and something held me back at the time. So I think there is a mixture of science and pseudoscience as you suggested too.

All the love we need we can get direclty through the Ruach haQodesh through trusting in Messiah. Nevertheless we can still eat and drink clean. kosher food and surround ourselves with natural frequencies.
