The words aphala-akanksibhih means those who have no desire for rewards. Those devout and evolved jivas or embodied beings with ardent faith, who are imbued with the consciousness that all their actions are humble offerings of worship rendered to the Supreme Lord Krishna or any of His authorized incarnations and expansions as revealed in Vedic scriptures; performing the three aforementioned types of austerity of the physical body, speech and mind are known to be in sattva guna the mode of goodness.
