道生一，一生二， 二生三，三生万物。 万物负阴而抱阳，冲气以为和 The Tao produced One;One produced Two;Two produced Three;Three produced All things. All things leave behind them the Obscurity (out of which they have come), and go forward to embrace the Brightness (into which they have emerged), while they are harmonized by the Breath of Vacancy
