The purpose of yoga isn't to "empty your mind" it is sort of the opposite. It is to cultivate awareness. Awareness of your thoughts, feelings, body, and surroundings.
The purpose of such meditation is to empty oneself. . . . [Satan] is happy to invade the empty vacuum of your soul and possess it.
This is, yet again, an example of religious leaders trying to dictate every aspect of your life. You aren't allowed to make even simple decisions for yourself, like which class to take at the gym? Seriously? Tell me again how you're not cult-like?
Let's just say the goal was "emptiness." So by not thinking, you're emptying your soul? That is an interesting theory. I guess, by your logic, we should avoid things like sleeping or medically necessary anesthesia. Avoiding sleeping is actually sort of Biblical. So Christians, maybe you should stop sleeping, okay? Because Satan.
Also, by your logic, "emptying oneself" might also include totally not thinking rationally and maybe being completely stupid. Which might include suggesting things like, Satan is super eager to hop on into your soul at a moment's notice.
satanic/demonic possession is ridiculous
