Why did the Buddha choose Mahakasyapa as his successor?

Buddha chose Mahakasyapa as his successor due to Mahakasyapa's deep understanding of his teachings and his exemplary spiritual practice. He was known for his asceticism, wisdom, and ability to grasp the essence of the Dharma without relying solely on Words. During the Flower Sermon, when Buddha silently held up a flower and Mahakasyapa smiled, it symbolized his profound insight into the non-verbal transmission of wisdom, confirming his suitability to carry on the teachings. Thus, Mahakasyapa became a pivotal figure in the early Buddhist community, ensuring the continuity of Buddha's message.
