“There is no way to attain enlightenment on one's own. Such a thing has never happened in infinite aeons. Shravakas and pratyekabuddhas who appear when a buddha is not manifest in this world can realize the twelve branches of interdependent origination and attain arhatship. They aren't, however, able to attain complete enlightenment and cannot benefit beings in a vast way; they can only liberate themselves from the sufferings of cyclic existence, and their realization is far from complete enlightenment. In the Sutrayana, one studies and analyzes the teachings and texts, but no matter how extensive the teachings are, they are all based on the essential nature. The Buddha provided many different levels of teaching, which can be categorized into provisional and definitive meaning. These teachings can be studied, analyzed, and examined, but they're not so easy to understand. For instance, when great scholars, such as khenpos, give detailed Sutrayana teachings, the students listen, reflect on, and analyze the teachings and debate on them. They rely on the texts that they have been taught.” EnlightenmentDharmaVajrayanaThe Vast And Profound Vehicles Book:An Ocean of Blessings: Heart Teachings of Drubwang Penor Rinpoche Source: An Ocean of Blessings: Heart Teachings of Drubwang Penor Rinpoche
