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.
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind."
(Gampopa to Düsum Khyenpa, in "The First Karmapa", KTD Pub, p254)
“If you recognize the world of appearance and existence as the mind, realize the mind itself as empty, and have no grasping at the superiority of your realizations — this is the ultimate view."
(Chegom Dzongpa, in "The Book of Kadam", Wisdom Pub, p609)
