6.459

一間者，唯為一生所間不得涅槃故名一間，間是間染，舊名一種子，謂不正也。依梵本云翳迦鼻親迦，可云一種子。然此中說，翳迦鼻指迦，此云一間，故不得云一種子。此人人中得一來果進斷第七品惑，斷第八九二品惑，唯第九品或潤於天業唯受天一身即般涅槃，更不還來生人中故名一間，此中且據人得一來果往於天上般涅槃。若於天上得一來果，即來人中唯受一身即入涅槃名為一間。言永斷上品中品者，束九為三品，上中令盡故言斷上中品，於下品纏生未斷盡名餘，下品中般三人，初人利根初捨欲界死蘊，更於色界十六處中隨一中有現前即斷餘惑而般涅槃，此是有餘涅槃。第三人未斷餘結不自知唯受中有支意往趣生有，依雜心說三種中般皆趣生有：一者、欲界不遠即般有餘；二者、行半；三者、垂至色界方般有餘，以未斷結不自知故皆趣生有。

An ekavīcika ('one interval'): because one is obstructed from attaining nirvāṇa by only one rebirth, one is called an ekavīcika ('one interval'); vīci ('interval') means defiled obstruction. Formerly it was termed 'one seed' (ekabījika), which is improper. According to the Sanskrit text, it says ekabījika, which could be translated as 'one seed'. However, what is stated here is ekavīcika, which translates here as 'one interval'; hence it must not be called 'one seed'. When this person attains the fruit of once-returner among humans, progresses to sever the seventh grade of defilement, and severs the eighth and ninth grades of defilement, only the defilement of the ninth grade moistens karmic existence in heaven; taking only a single physical existence in heaven, they then enter parinirvāṇa and no longer return to be born among humans, hence being called an ekavīcika. Here it is provisionally explained in terms of a person attaining the fruit of once-returner and going to heaven to enter parinirvāṇa. If one attains the fruit of once-returner in heaven, one immediately comes to the human realm, takes only a single body, and then enters nirvāṇa; this is called an ekavīcika. Regarding the statement 'permanently severing the superior and intermediate grades': when the nine grades are grouped into three, the superior and intermediate are brought to an end, and therefore it is said that 'the superior and intermediate grades are severed.' The unsevered residue of the lower grades of entanglements of rebirth is called the remainder. Among those who attain parinirvāṇa in the intermediate state, there are three types of persons: the first person, of sharp faculties, upon first relinquishing the aggregates of death in the desire realm, confronts the intermediate existence in any one of the sixteen places in the form realm, immediately severs the remaining defilements, and enters parinirvāṇa; this is nirvāṇa with remainder. The third person, not having severed the remaining fetters and lacking self-knowledge, merely experiences the intermediate existence and intends to proceed toward the rebirth existence. According to the Saṃyuktābhidharmahṛdaya, all three kinds of intermediate parinirvāṇa-attainers proceed toward rebirth existence: first, one who attains nirvāṇa with remainder not far from the desire realm; second, one who attains it midway through the journey; third, one who attains nirvāṇa with remainder only when nearly reaching the form realm; because they have not severed the fetters and lack self-knowledge, they all proceed toward rebirth existence.
