Religion was very important in the Khmer Kingdom. Over time, many people followed Buddhism, a religion that teaches people how to live a peaceful and kind life. Buddhism does not focus on one powerful god. Instead, it teaches people to understand their own actions and thoughts.
Buddhists believe that life includes suffering, but people can reduce suffering by being kind, calm, and thoughtful. Important ideas include not hurting others, telling the truth, and helping those in need. Buddhists believe that what you do in life matters, and good actions lead to better outcomes.
Buddhism also teaches about meditation, which means sitting quietly and focusing the mind. This helps people feel calm and understand themselves better. Monks practiced meditation and lived simple lives, often in temples.
Many Khmer temples, including Angkor Wat, became Buddhist temples over time. Buddhism helped shape Khmer ideas about peace, balance, and respect for all living things, and it is still an important religion in Southeast Asia today.
