The two truths
Two true ways to talk about the world: the everyday way that works, and the deeper way that's exact.
One of Buddhism's most useful ideas is that a statement can be true on more than one level. This is the teaching of the two truths (Sanskrit satyadvaya). It heads off a common confusion: when Buddhist texts say the self, or even a chariot or a cloud, doesn't "really" exist, they are not calling everyday life a lie. They are pointing to two valid registers of truth.
The first is conventional truth (Sanskrit saṃvṛti-satya). This is the ordinary, practical level where chairs are chairs, you are you, and "please pass the water" makes perfect sense. Conventional truths are genuinely true for getting through life; nothing here is being dismissed.
The second is ultimate truth (Sanskrit paramārtha-satya). Looked at closely, everything we name turns out to be a temporary assembly of parts and conditions, with no fixed, independent core holding it together. A "chariot" is just wheels, axle, and frame arranged a certain way; there is no extra chariot-essence hiding inside. Ultimately, things exist this way — dependently and fluidly — rather than as solid, self-standing units. (Note this does not mean things are nothing: dependent existence is still existence, just not the fixed kind we imagine.)
The point is that both levels are true at once, like seeing that a movie is both a gripping story and just light on a screen. The idea is old — already at work in early Buddhist analysis — but different schools developed it with great subtlety, and it is especially load-bearing in Madhyamaka, the "middle way" philosophy systematized by the teacher Nāgārjuna (around the second century CE). Schools debate exactly how the two relate. But the shared move is gentle and freeing: honor the conventional world fully, while not mistaking it for something more fixed than it is.
