釋禪波羅蜜次第法門 3.169

3.169

復次，行者過去修習事理諸禪三昧，雖未得證成就，而已經修習今世善根時熟，藉修止為緣，悉皆開發，此亦是習因善根發也。類等佛命「善來」，無漏即發，三明八解一時具足。料揀亦有漏亦無漏，乃至非有漏非無漏，類例可知。

Furthermore, if a practitioner in past [lives] cultivated and practiced various dhyānas and samādhis in terms of phenomena and principle, although they had not yet attained realization and fulfillment, because they had already cultivated and practiced them, when their wholesome roots in the present life ripen, relying on the cultivation of stopping as a condition, all of them unfold and develop. This is also the manifestation of wholesome roots from habitual causes. It is analogous to when the Buddha called out, 'Welcome (ehi)!', whereupon the undefiled immediately manifested, and the three knowledges and eight liberations were simultaneously perfected. The discernment of both-defiled-and-undefiled, up to neither-defiled-nor-undefiled, can be known by similar analogy.
