Sosan, also known as the Third Zen Patriarch, was a Chinese Zen teacher who lived during the 6th century. His teachings had a profound impact on the lives of his students and followers, and his influence can still be seen in the practice of Zen Buddhism today.

One of the main ways in which Sosan's teachings impacted his students and followers was through his emphasis on the practice of meditation. Sosan believed that through meditation, one could attain a state of enlightenment and ultimately find inner peace and happiness. He taught his students various meditation techniques, such as focusing on the breath or on a specific koan (a paradoxical question or statement), to help them quiet their minds and reach a state of clarity and understanding.

Sosan's teachings also emphasized the importance of living in the present moment and letting go of attachments to the past and future. This concept, known as "mindfulness," is a central tenet of Zen Buddhism and is still widely practiced by his followers today. Sosan believed that by living in the present moment, one could find true happiness and freedom from suffering.

Another key aspect of Sosan's teachings was the idea of non-duality, or the understanding that all things are interconnected and ultimately one. He taught his students to see beyond the illusions of the ego and to recognize the inherent unity of all beings. This concept is still a fundamental part of Zen Buddhism and has had a profound impact on the lives of his students and followers, helping them to cultivate compassion and empathy for others.

Sosan's teachings also emphasized the importance of self-reflection and self-discovery. He encouraged his students to look within themselves and to question their own beliefs and perceptions. By doing so, they could gain a deeper understanding of themselves and the world around them. This practice of self-inquiry is still a crucial aspect of Zen Buddhism and has helped many of Sosan's followers to find clarity and purpose in their lives.

Overall, Sosan's teachings had a significant impact on the lives of his students and followers. Through his emphasis on meditation, mindfulness, non-duality, and self-inquiry, he helped them to find inner peace, clarity, and a deeper understanding of themselves and the world. His teachings continue to inspire and guide Zen practitioners today, making him a revered figure in the history of Zen Buddhism.
