Dependent origination (Pratītyasamutpāda) is the structural insight beneath all the rest: everything in conditioned existence arises from prior conditions, and in turn conditions what follows. Nothing exists independently or permanently. It is the basis for both impermanence and no-self. Closely paired is Śūnyatā, emptiness, not nihilism but the absence of inherent, independent existence in anything.
Driving this conditioned arising is karma, intentional action and its fruit, the choices that condition what comes next. Buddhism holds karma without a permanent self to carry it; its full treatment, with that difference drawn out, lives on Karma.
Later Buddhist thought gave the idea its most beautiful image: Indra's net, an infinite net stretching in every direction, a jewel at each knot, every jewel reflecting all the others. Touch one, and the whole net trembles. The Zen teacher Thich Nhat Hanh gave it a modern word, interbeing. A sheet of paper, he wrote, holds the cloud that became the rain, the sun, the forest, the logger and the bread that fed him: to be is to inter-be. The plainest secular name for the same insight is systems thinking. You cannot understand a part in isolation, because what a thing is includes its relationships.
This is why YogoLogo is built as a web, not a checklist: the eight limbs are jewels in one net, each reflecting and strengthening the others.
An honest edge: interbeing describes a world with no separate, permanent self, the same ground as no-self, and a real difference from the yogic Purusha*, the witness at the centre of the Layered Self. Both agree the isolated self is an illusion; they describe what remains differently.*
