This chart represents my understanding of how one progresses on the path to Buddhahood and the belief that all sentient beings are on such a path, even if that is not yet their conscious goal. It is very simplified and does not reflect many of the details or nuances within the various categories. It shows the difference in goals among the world religions and the two main branches of Buddhism. It also provides basic information about what the other religions and the three or four categories of Buddhist practice include—the level of attainment involved in each and the time required to become accomplished. Finally, it lists some of the vows and actual practices done in each of these categories. Please remember that the chart represents generalizations about the various systems of belief and is not absolutely true for any given practitioner within that system.

Initial Stage Lesser Vehicle Stage* Mahayana Stage
GOAL To stop non-meritorious (evil) behavior and practice good behavior to accumulate necessary merit so as to gain high status and a favorable rebirth in the future. In Buddhism this is seen only as a provisional goal and not as an end in itself. However, mastery of this stage is necessary to progress to higher levels. To escape suffering of samsara (cycle of birth and death). This includes Sravakas or Arhats (Lo-hans) as well as the Pratyekabuddhas who obtain liberation on their own without a teacher in their current lifetime. This is also seen as a provisional goal or respite on the way to Buddhahood whereby the conflicting emotions are eliminated but the goal of ultimate nirvana has not been reached. The superior goal of the Bodhisattva to bring all beings to complete enlightenment or ultimate nirvana before gaining the goal of Buddhahood for one’s self. Here the double veils of conflicting emotions and primitive beliefs about reality have both been lifted and one achieves complete enlightenment.

*In most sources the term “hinayana” is used to describe the Lesser Vehicle. It is believed that this was a mistranslation of very early texts as “hina” is considered a very insulting and derogatory term in Pali and Sanskrit. The word used in Tibetan and Chinese is translated as “lesser” without that connotation to denote that a lesser goal (short of full Buddhahood) is sought. Some use the term Sravakayana as this is the vehicle of the Sravakas or Arahats. Others refer to Early Buddhism or Conservative or Fundamental Buddhism to describe those who follow this path as compared to the Mahayana path. And some only want to refer to Northern and Southern Buddhism, but that does not portray the essential differences in goals of the two groups. Whatever this path is called, it should not be considered inferior in its methods or teachings and they were taught by Shakyamuni Buddha as what was appropriate for those living when He taught and for many people today. As shown on this chart, the Mahayana followers, must also master or understand these teachings to become accomplished. However, the use of any derogatory term that is insulting in its meaning is not appropriate and should not be used.

**It is not correct to assume that those following the lesser vehicle do not develop compassion or bodhichitta. H.H. Dorje Chang Buddha III has taught that one cannot become an Arhat without having Bodhichitta. These categories should only be considered as guides and used for reference.

+ Although the truths of these practices are the same for the followers of the Lesser Vehicle and Mahayana, the levels of realization of these factors are different. You should  readExpounding the Absolute Truth Through the Heart Sutra to understand this.
