Siddhartha, also known as Gautama, the founder of Buddhism, was born about 2500 years ago. This was a time of rapid change in the lives of people, some kings in the mahajanapadas were growing more powerful. New cities were developing, and life was changing in the villages as well. Many thinkers were trying to understand these changes in society. They also wanted to try and find out the true meaning of life. The Buddha belonged to a small gana known as the Sakya gana, and was a kshatriya. When he was a young man, he left the comforts of his home in search of knowledge. He wandered for several years, meeting and holding discussions with other thinkers. He finally decided to find his own path to realisation, and meditated for days on end under a peepal tree at Bodh Gaya in Bihar, where he attained enlightenment. After that, he was known as the Buddha or the Wise One. He then went to Sarnath, near Varanasi, where he taught for the first time. He spent the rest of his life travelling on foot, going from place to place, teaching people, till he passed away at Kusinara. The Buddha taught that life is full of suffering and unhappiness. This is caused because we have cravings and desires (which often cannot be fulfilled). Sometimes, even if we get what we want, we are not satisfied, and want even more (or want other things). The Buddha described this as thirst or tanha. He taught that this constant craving could be removed by following moderation in everything. He also taught people to be kind, and to respect the lives of others, including animals. He believed that the results of our actions (called karma), whether good or bad, affect us both in this life and the next. The Buddha taught in the language of the ordinary people, Prakrit, so that everybody could understand his message
