The Bodhisattva path is seen to be a superior path to that of the Pratyekabuddhas. The path of Pratyekabuddhas is considered selfish because they seek enlightenment and nirvana for themselves and deny the suffering of humanity. This statement sounds to be an oxymoron to me. So, if the pratyekabuddhas were selfish, their consciousness was inevitably bottled in an "I" and nirvana should be impossible for someone with a bottled consciousness. How can someone attain nirvana if they are heartless towards the suffering of humanity? And why is it impossible to help others after reaching Nirvana?
