答：欲界諸惡難斷難破難可越度，故初定建立五支為牢強對治，第二定重地極喜難破難可越度，故第三立五為強對治，初及第三俱無如是難斷等法，是故二四唯立四支，復次為對治欲界增上五欲境貪故，及為治第二定五部重地愛故，初三各五，復次為欲隨順超定法故，其義云何，如從初禪超入第三，從五入第二禪超入第四，從四入四，是故初三立五，二四立四間若爾如從三禪超入空處處處亦應立有五支，從第四禪超入識處，識處亦應立有四支。

Answer: The various evils of the desire realm are difficult to sever, difficult to break, and difficult to surmount; therefore, the first dhyāna establishes five limbs as a solid and powerful antidote. The profound stage of extreme joy in the second dhyāna is difficult to break and difficult to surmount; therefore, the third establishes five as a powerful antidote. The first and third [higher alternatives] both lack such dharmas that are difficult to sever, etc.; therefore, the second and fourth establish only four limbs. Furthermore, it is in order to counteract the craving for the five senses' objects predominant in the desire realm, and in order to counter the attachment to the profound stage of the five categories in the second dhyāna, that the first and third each have five. Furthermore, it is in order to accord with the method of leap-over concentration (vyutkrāntaka-samādhi). What does this mean? It is like leaping from the first dhyāna into the third, [and leaping from the second dhyāna into the fourth,] from five entering [five, and] from four entering four; therefore, the first and third establish five, and the second and fourth establish four. Question: If so, then just as one leaps from the third dhyāna into the sphere of boundless space, the sphere of boundless space should also establish five limbs; and leaping from the fourth dhyāna into the sphere of boundless consciousness, the sphere of boundless consciousness should also establish four limbs.
