I'm not sure what you're getting to. As a Mahayana path, those who follow the Zen methods aspire to be bodhisattvas and buddhas who liberate sentient beings. It is not the path of the small minded who want only to escape from the cycle of birth and death, but the way of those who realise the inseparability of samsara and nirvana.
"If the Buddha-Nature is seen, there will be no seeing of a nature in any thing."
(Nirvana Sutra, T12n374p521b3; tr Yamamoto)
"Neither cultivation nor seated meditation — this is the pure Chan of Tathagata."
(Mazu Daoyi, X1321p3b23; tr. Jinhua Jia)
“Don’t rashly seek the true Buddha;
True Buddha can’t be found.
Does marvelous nature and spirit
Need tempering or refinement?
Mind is this mind carefree;
This face, the face at birth."
(Nanyue Mingzan: Enjoying the Way, tr. Jeff Shore; T2076p461b24-26)
