Two contradictory passages in the Majjhima Nikaya

In [MN 22](https://www.accesstoinsight.org/tipitaka/mn/mn.022.than.html) in the end of the simile of the raft the Buddha says that the arahant has relinquished both what is skillful and what is unskilful: > "Understanding the Dhamma as taught compared to a raft, you should let go (pahātabbā) even of Dhammas, to say nothing of non-Dhammas." Why is then the Buddha described in [MN 88:17](https://suttacentral.net/mn88/en/suddhaso) like so: > "The Tathāgatha great king has abandoned all unwholesome states and possesses (samannāgata) wholesome states"
