"Pre-sectarian" refers to the Buddhism in the period between the first discourse of Gautama Buddha until the first enduring split in the Sangha, which occurred between the second (4th
century BCE) and third Buddhist council (~250 BCE). Pre-sectarian Buddhism is the Buddhism presupposed by the early Buddhist schools as existing about one hundred years after the death of
the Buddha. There was a rough body of sacred literature that a relatively early community maintained and transmitted which contains the Buddhas original teachings. Pre-sectarian Buddhism was
formulated by the Buddha and his immediate followers after his death.
Pre-sectarian Buddhism is simply Buddhism returning to the core teachings of the Buddha. These teachings include the middle way, dependent origination, the four noble truths, and the eight
fold path, and the five precepts. Much of the monastic rules came after the teaching of the Buddha and the Buddha himself reached a higher state of being own his own. Everyone has this ability,
we simply encourage others to learn the teachings of the Buddha and find their own path to enlightenment without any attached dogma or personal judgement.
