To an outsider, Buddhism might appear too old and convoluted to tap into. Under its three main schools of thought, Theravada, Mahayana, and Vajrayana there are many subsets according to the different cultures and times that adopted it throughout its 2500-plus years of existence. Some argue for comprehensive studies, building an entire framework for Buddhism by tracing its history. Lama Anagarika Govinda writes in his essay “From Theravada to Zen,” "In order to understand the sacred scriptures of Buddhism, we must ... be familiar with the living stream of tradition, as it has come down to us from the days of the Buddha, in an unbroken continuity."Even so, there remain accessible keys to unlocking the door of Buddhism.
