大般涅槃經義記 6.155

6.155

Among the ten, the first five are names of his own virtues, and the latter five are his titles of virtue in transforming others. Among those of his own virtues, the first two form a pair: the former is the perfection of the path, and the latter is the culmination of cessation. As for 'Tathāgata' (Thus-Come), its multiple meanings are as below; relying on Nāgārjuna's explanation, he mounts the path of reality as it is to come and achieve correct enlightenment, hence he is called 'Tathāgata'. As for 'Arhat' (One Worthy of Offerings), its multiple meanings are as below; to state the essentials, he corresponds with the realization of cessation, so he is called 'worthy' (arhat); furthermore, he is worthy of offerings, and offering is called 'worthiness'.
