The Buddha, in Chapter 2, tells his contemporary disciples that the teachings they had been taught were only a stepping stone to a great way of practice which he says is not a Sravaka practice, not a Pratyekabuddha practice, and not a Bodhisattva practice, but it is in a way a combination of all of those practices. Instead of there being three different ways of practicing according to a persons capacity, there is in fact only one way of practicing. That single way of practicing is on the one hand combining all the three different ways into one, and – now this is important – it is the awareness and realization that there is an even higher state than Nirvana as a goal. There is the fundamental truth that all Buddhas are awakened to and that is Anuttara-samyak-sambodhi.
