The correct option is The first sermon.
Explanation
The Sarnath Lion Capital, erected by Emperor Ashoka, is one of the finest examples of Mauryan sculpture. It was constructed to commemorate a pivotal event in the life of Gautama Buddha at the Deer Park in Sarnath.
Analysis of the Event:
- Dhammachakrapravartana: This term literally translates to "Turning the Wheel of the Law" (Dharma). It refers to the First Sermon delivered by the Buddha to his five disciples after attaining enlightenment.
- Symbolism: In Buddhist art, this event is symbolized by the Wheel (Chakra). The Sarnath pillar originally supported a large wheel (Dharmachakra) on top of the four lions, signifying the proclamation of the Dharma in all directions.
Comparison with Other Events:
- The Birth (Jati): Symbolized by the Lotus and Bull.
- The Enlightenment (Mahabhinishkramana/Nirvana): Symbolized by the Bodhi Tree.
- The Mahaparinibbana (Death): Symbolized by the Stupa.
Key Takeaway:
The Dhammachakrapravartana marks the Buddha's First Sermon at Sarnath, where he set the "Wheel of Law" in motion, a moment monumentalized by Ashoka through the Sarnath Lion Capital.
