Samudaya, in the context of Buddhist teachings, refers to the second of the Four Noble Truths, which identifies the cause of suffering as desire or craving. This concept highlights that attachment and longing for sensory pleasures, existence, or non-existence lead to suffering in life. Understanding samudaya is crucial for grasping the broader framework of Buddhism and its teachings on the nature of suffering and the path to liberation, especially during the philosophical developments from Vedic India through the Maurya Empire.
