Shankaracaria mentions asarto the deeply empty or unsatisfactory nature of things. He calls it asara, which means without essence. All things in the world are empty, empty of essence. They cannot give lasting satisfaction. None of it can give us lasting fulfilment. If they could give the happiness they seem to promise, everybody wants them. So there's a promise there that the'll give you a lot of happiness. But they can't. That's an astonishing thing which we don't look at. We think, what we think is we think, oh, let me try another restaurant. Let me try another acar, another relationship er, another spiritual teacher.
