Buddhism originated around 2500 years ago in India with Siddhartha Gotama, known as the Buddha, who achieved enlightenment at age 25. The core of Buddhism involves following a moral life, being mindful of one's thoughts and actions, and developing wisdom to escape samsara, the continuous cycle of rebirth and suffering, ultimately reaching nirvana. There are over 300 million Buddhists worldwide who practice in different traditions such as meditation, painting mandalas, or celebrating festivals like Dharma Day or Losar, but all are united in following the Four Noble Truths of suffering, its cause, its end, and the path to end it.
