Here are some well-known global figures who spoke about Jainism or its principles:

• Mahatma Gandhi — openly discussed Jain values, especially ahimsa (non-violence), and his philosophy was influenced by Jain ethical principles.
• Virchand Gandhi — a key Jain lay leader who represented Jainism at the World Parliament of Religions in Chicago in 1893 and spoke widely about Jain thought.
• Acharya Lokesh Muni — a prominent modern Jain monk known for interfaith dialogue and speaking on Jain philosophy and ethics to audiences worldwide.
• Acharya Mahapragya — a respected Jain monk and reformer who lectured internationally, promoting Jain ethics, non-violence, and spiritual practice.
• Sadhvi Siddhali Shree — a contemporary Jain nun, filmmaker, and speaker who has given talks and presentations on Jainism and its social applications in the West.

If you’d like, I can look for specific talks, dates, or venues for any of these individuals.
