Nowadays? Christian religious structures have used that technique since the start of the religion. It's a fear based mindset, and as such you can easily tell it's "evil". Demonise everything else, set yourself up as the one truth.
Yeah, you said the key words. Quote: "since the start of the religion." = Since the "creation of the church religion" was formed and ever since then, MAN has tried to brainwash and mindcontroll the people into beliving. As we know from the "bible" that the church leaders have turned the belief of God, and turned it into poo. Example: The "Children Of God" used to have a Animal Sacrifice(s) towards God, and sadly the practice is now dead, because of the church leaders overtaken it into something else.


The mystics - Carmelites mostly - spoke about this. They didn't use 'candle gazing' but they spoke
about making quiet the internal cravings and noise. St. Teresa of Avila would spend hours 'water gazing'. They didn't call it that, and to this
day the Catholic Church doesn't say that's what it was, but she did spend hours gazing at running water.
