Mahāyāna Buddhists criticized Nikāya Buddhism as follows: The two groups, śrāvakas and pratyekabuddhas, comprise a so-called Hinayāna or lesser vehicle. Their purpose is solely for their own benefit, not the benefit of others; the salvation that they seek is only theirs. On the other hand, bodhisattvas comprise the so-called Mahāyāna or greater vehicle. This is because their aim is to lead others to salvation through their practice of Buddhism, with the benefit of others as their top priority. From the position of the Mahāyāna, śrāvakas and pratyekabuddhas can never become buddhas. This is because they avoid practices for the benefit of others which are necessary to become a buddha. Only the bodhisattvas, who work for the benefit of others, have the capacity to become buddhas.
