Has anyone tried this - or any aspect of it?

"Mindfulness is definitely in fashion these days. People everywhere report that it has changed their lives, and the scientific research on the practice is booming. But an interesting change is happening in the world of mindfulness. A different type of mindfulness – nondual mindfulness – is growing in popularity. Furthermore, trustworthy scientific people (like Sam Harris) are making incredible claims about it. They are saying it is superior to conventional mindfulness, that it gives you access to a profound form of happiness that is available at will, and even that it is synonymous with spiritual awakening and/or enlightenment! They also claim that this form of awakening can be learned."

P.S. Not 100% sure whether Sam Harris is a "Trustworthy, scientific person" or not. :)
