Immediately after attaining full awakening at Uruvelā under the Bodhi tree, the Buddha (`Bhagavā`) spent a night contemplating `paṭiccasamuppādaṃ` (dependent origination) in three watches. He systematically understood that the phenomenal nature of experience - resulting in `dukkha` (suffering) - can be traced through a linked set of causes ultimately back to ignorance (`avijjā`). The cessation of ignorance then leads to the cessation of this chain of causes and thus the end of experienced `dukkha`. This profound realisation led him to utter inspired verses (`udāna`) affirming this understanding of the phenomenological framework has enabled him to dispel all doubts and deconstruct the framework, resulting in awakening.
