The correct answer is (c).
Mahabhinishkramana is the Sanskrit term for “Great Departure”. It refers to the event in the Buddha’s life when he left his home and family to pursue a life of spiritual enlightenment.
The Buddha was born into a wealthy family in Lumbini, Nepal. He was raised in a palace and had everything he could ever want. However, he was troubled by the suffering he saw in the world. One day, he left his home and family to seek a way to end suffering.
He wandered for six years, studying with different teachers and practicing different forms of meditation. Eventually, he sat down under a Bodhi tree and vowed not to rise until he had found enlightenment. After 49 days of meditation, he attained enlightenment and became the Buddha, or “the Awakened One”.
The Buddha’s Mahabhinishkramana is a significant event in Buddhist history. It marks the beginning of his journey to enlightenment and the start of his teaching career.
