What is non-duality?

Non-duality is covered in a lot of different traditions. It comes from Advaita Vedanta primarily, because what we call non-duality is derived from Advaita. which means “Not two.” But other traditions study it as well. Buddhism, Sufis and Dervishes talk about non-duality.

In a nutshell, poetically, you could say there is just oneness, there is no other, there is no second. This however brings up the idea of a me, an individuality, with a center of some kind. That’s two. It is but an illusion obscuring the fact that there’s just oneness there’s unicity only.

I tend to talk a lot about ceasing to do because it is helpful to minimize our our volitional action. Basically this "me" that is constantly trying to do just reinforces the feeling of a "me" trying to do something and get somewhere.

This ceasing to do can start in very very simplistic ways. We typically do so much more than is even necessary. I mean, if you just check your own posture for example. If you're sitting or standing perfectly upright it requires very little muscle to stay upright, but if you're leaning we have to do a lot to fight gravity or we'll collapse.

How do you come up with a question? Does it matter what we ask?

I would say it's best not to ask about hypotheticals. You want to try to make any question asked relevant to yourself not other people. If you ask a question like "How could you go with this philosophy", it doesn't really apply.
