Here it is worthwhile to understand the difference between: 'Buddhism' and the 'Dhamma' 'Buddhism' is referred to as the Totality of 'Teachings' available to Buddhists within a certain locality at a certain time, whilst the 'Dhamma' is the collection of universal laws which are prevalent irrespective of the fact that a Buddha has re-discovered them or not. As 'Buddhism' spread from place to place and from time to time, the Teachings got assimilated to the local existing '-isms' and became known and refered to by terms such as 'Maha-yana', Hina-yana', 'Vajra-yana', Zen etc. Thera-vada is another synonym used for 'Hina-yana' and is the 'Buddhism' practiced by people in Countries such as Burma, Thailand, Sri-Lanka. Maha-yana and Zen are the traditions of people in Japan, Korea, China ets. Vajra-Yana the tradition of Tibetan Lamas and their followers. However the important thing is that the Dhamma is universal.
