What is meant by giving up the teachings?

Buddha says > So you should train like this: ‘I will not tell a lie, even for a > joke.’ Tasmātiha te, rāhula, ‘hassāpi na musā bhaṇissāmī’ti Dhamma as taught by Buddha is not a lie therefore one should not say things which contradict Buddha. However Buddha in [MN 22](https://suttacentral.net/mn22/en/sujato?lang=en&layout=linebyline&reference=none¬es=asterisk&highlight=false&script=latin) asks to give up Dhamma. > By understanding the simile of the raft, you will even give up the > teachings, let alone what is against the teachings. > > Kullūpamaṁ vo, bhikkhave, dhammaṁ desitaṁ, ājānantehi dhammāpi vo > pahātabbā pageva adhammā. What is meant by giving up the teachings ? For example- How do you give up the teaching that Sabbbe Dhamma Anatta? or Sabbe Sankhara Anicca? or Sabbe Sankhara Dukkha?
