Buddhism is not religion in the usual sense of the word. It is a method of investigation that allows you to work skillfully with the positive potentials and negative energies of your own mind. The teachings of the Hinayana represent the most fundamental instructions of the Buddha, which are central to everything that follows. Hinayana studies, therefore, are basic to any training in Buddhism.
In the Nalandabodhi Path of Study, Hinayana studies introduce you to Buddhism as a science of mind, or method of investigation. Your study of the Hinayana is divided into two courses: The first course covers the ground or view of Hinayana, and the second covers the Hinayana path and its results.
