Final answer:
Siddhartha Gautama, known as the Buddha, achieved enlightenment under the bodhi tree, similarly to how Jesus experienced spiritual transformation. This event marked the founding of Buddhism and significantly influenced Indian culture.
Step-by-step explanation:
Under the bodhi tree, Siddhartha Gautama, who later became known as the Buddha, achieved enlightenment, which is an event that resembles the spiritual transformation experienced by Jesus Christ in Christian theology. Around 500 B.C.E., Siddhartha, a prince surrounded by luxury, chose a path of poverty and spiritual devotion. After years of searching and following a middle way between indulgence and asceticism, he meditated under the sacred fig tree and vowed not to rise until he had found the truth about life and suffering. This pivotal moment led to his enlightenment and his teachings formed the foundation of Buddhism, impacting Indian culture, religion, and art significantly.
