第二、互證。此約第三隨便宜、第四對治、第五相攝、第六通觀，四種妙門中論證相。所以者何？此四種妙門，修行方便無定次第，故證亦復迴互不定。如行者當數息時，發十六觸等諸闇證、隱沒、無記、有垢等法，此禪即是數息證相之體，而今不定。或有行者於數息中，見身毛孔虛疎，徹見三十六物。當知於數息中，證於隨門。

Second is reciprocal realization. This discusses the characteristics of realization in terms of the four wondrous gates: the third, according with convenience; the fourth, remedying; the fifth, mutual subsumption; and the sixth, universal contemplation. Why? Because in these four wondrous gates, the expedients of cultivation have no fixed order, and therefore the realizations likewise reciprocally vary without fixity. For instance, when a practitioner is counting breaths, if the sixteenth touches and other dark realizations, obscurity, non-definition, defilement, and so forth arise, this dhyāna is the essence of the characteristics of realizing the counting of breaths, yet now it is not fixed. Or there may be a practitioner who, while counting breaths, sees the pores of the body as hollow and open, thoroughly seeing the thirty-six components [of the body]. One should know that while counting breaths, he realizes the gate of following.
