Skeptical Participants
Some time ago, we had a professor/scientist coming to our Module 1 retreat, dragged along by his wife who wanted to improve their intimate life and get pregnant. He was sceptical about energy and spirituality. I whispered to him "Since you came here anyway, you may as well use this time to stay open. You don't have to do anything you don't like."
On Day 3 of the retreat, 3 of our assistants have been holding him in their arms because his body was in an intense uncontrollable energetic experience which he later described as an intense blissful energy passthrough. It lasted for an hour or so.
After that experience, all his scepticism was out of the window. He even could explain the phenomenon himself from the scientific perspective. Consequently, he enrolled into the 1 year program dragging his wife along, because she got pregnant and her sexual energy was re-directed to other divine purposes.
Some people would say MIRACLES.
We say TANTRA.
