 In later years, Sarvāstivādin (Vaibhāṣika) and Sautrāntika, Madhyamaka (from the first century CE onwards) and Yogācāra (ca. sixth century CE onwards) became the dominant schools. Our investigation of the theory of the two truths will briefly focus on how these schools have received, interpreted and understood it. Although all these schools regard the theory of two truths as the centrepiece of the Buddha’s philosophy, all have nevertheless adopted very different approaches to the theory. As we shall see each understood and interpreted the two truths in different ways, and are often fundamentally and radically opposed to each other.
