Buddhism is a path of practice and spiritual development leading to Insight into the true nature of reality. Buddhist practices like meditation are means of changing yourself in order to develop the qualities of awareness, kindness, and wisdom. The experience developed within the Buddhist tradition over thousands of years has created an incomparable resource for all those who wish to follow a path — a path which ultimately culminates in Enlightenment or Buddhahood. An enlightened being sees the nature of reality absolutely clearly, just as it is, and lives fully and naturally in accordance with that vision. This is the goal of the Buddhist spiritual life, representing the end of suffering for anyone who attains it.
Because Buddhism does not include the idea of worshipping a creator god, some people do not see it as a religion in the normal, Western sense. The basic tenets of Buddhist teaching are straightforward and practical: nothing is fixed or permanent; actions have consequences; change is possible. So Buddhism addresses itself to all people irrespective of race, nationality, caste, sexuality, or gender. It teaches practical methods which enable people to realise and use its teachings in order to transform their experience, to be fully responsible for their lives.
There are around 350 million Buddhists and a growing number of them are Westerners. They follow many different forms of Buddhism, but all traditions are characterised by non-violence, lack of dogma, tolerance of differences, and, usually, by the practice of meditation.
