How do the sutras, vinaya texts, and Jataka stories describe the Buddha’s life differently?

The various categories of Buddhist literature describe the Buddha’s life with different emphases and narrative structures:

• Sutras: These discourses focus on the person of the Buddha, detailing his renunciation, practice of austerities, enlightenment, and passage into nirvana. While early sutras provide little detail on his childhood, they serve as the primary source for his teachings and individual life events. Later Mahayana sutras, such as the Lotus Sutra, offer a different conception, portraying the Buddha as having achieved enlightenment eons ago and using "skillful methods" to feign his life events to inspire others.12
• Vinaya Texts: These texts focus on monastic discipline and rarely present a continuous biography. Instead, they include accounts of the Buddha’s life as the context for specific rules, emphasizing his role as a teacher and the conversion of his early disciples.13
• Jataka Stories: These collections focus on the Buddha’s previous lives. They use past-life tales to illustrate moral maxims, identifying the Buddha as the main character in each story to connect his past incarnations to his present identity.1

While these early sources provide independent fragments, later texts—such as the Buddhacharita—attempted to synthesize these into a single, chronological life story to demonstrate how his deeds conformed to a universal pattern followed by all buddhas.1
