Bodhirājakumārasutta

Suttapiṭaka · Majjhimanikāya · Vol. 13 · Section 504

[504] "Prince (rājakumāra), this thought occurred to me: 'Whatever ascetics or brahmins in the past have experienced painful (dukkha), racking, piercing feelings (vedanā) arising from exertion, this is the utmost; there is none beyond this. Whatever ascetics or brahmins in the future will experience painful, racking, piercing feelings arising from exertion, this is the utmost; there will be none beyond this. Whatever ascetics or brahmins at present experience painful, racking, piercing feelings arising from exertion, this is the utmost; there is none beyond this. Yet by this piercing practice of austerities I do not attain any distinction in knowledge and vision (ñāṇa) worthy of the noble ones, surpassing the human state. Could there be another path (magga) to awakening?'"
