Why do buddhist's have different ways of worshipping their god?

Answer 1

This question relies on a misunderstanding of Buddhism: Buddhism does not recognize a god or gods.

In a nutshell, Buddhism is based on the teachings of Siddhārtha Gautama, also know as the Buddha (loosely translated as the Enlightened One, Awakened One, or Enlightened/Awakened Teacher). The Buddha devoted the latter part of his life to helping conscious or sentient beings end avidyā (ignorance), tanhā (craving), dukkha (suffering) through the recognition of pratītyasamutpāda (dependent origination), and śūnyatā (the nonexistence or denial of self).

Buddha, for whom the religion is named, is only a teacher, not an object of worship.

Now, the difference in the practices of Buddhism is the result of cultural differences in the two major philosophies and the places where it is observed and spread. Buddhism is divided (for lack of a better term) into two main branches: Mahāyāna (The Great Vehicle), and Theravada (The Teachings of the Elders). Both divisions originated in India but spread in different directions: Mahāyāna to the north and east, and Theravada to the north and west. Followers of Theravada emphasize the development of insight through analysis and literally the teachings of wise elders (the analysis of those who came before), while Mahāyāna defies easy explanation. Mahāyāna is the more open and plural form of Buddhism that seems to incorporate wise teachings from many sources.
