四、此一華葉其必舒己遍入一切，差別法中復能攝取彼一切法令入己內，是故即舒恒攝，同時無礙。經云「以一佛土滿十方，十方入一亦無餘」等。是謂第四相入門也。五、此一華葉必廢己同他，舉體全是彼一切法，而恒攝他同己，全彼一切即是己體，是故己即是他、他即是己，己即是他，己不立；他即是己，他不存，他己存亡同時顯現。經云「長劫即是短劫、短劫即是長劫」等。是謂第五相是門也。

Fourth, this single flower petal must extend itself to pervade and enter into all differentiated phenomena, and further be able to gather all those phenomena to make them enter within itself; therefore, being extended, it constantly gathers, simultaneously without obstruction. As the sūtra says: "Filling the ten directions with a single buddha-land, / And the ten directions entering into the one without remainder," and so forth. This is called the fourth gate of mutual interpenetration. Fifth, this single flower petal must abandon itself to be identical with the other, its entire essence being completely all those phenomena, yet it constantly gathers the other to be identical with itself, all of that [other] being completely its own essence; therefore, self is precisely other, and other is precisely self. Since self is precisely other, self is not established; since other is precisely self, other does not exist. The presence and absence of other and self are simultaneously made manifest. As the sūtra says: "A long kalpa is precisely a short kalpa, / A short kalpa is precisely a long kalpa," and so forth. This is called the fifth gate of mutual identity.
