user: 4무색정의 네 가지 선정을 알려주세요.

gpt: 4무색정의 처음 세 선정은 명상 대상, 즉, 그 선정이 존재하는 해당 무색계 영역의 본질에 따라 이름을 붙인 것이고, 마지막 비상비비상처정은 그 선정의 특징을 따라 이름을 붙인 것이다."四無色定", 星雲. 佛光大辭典 3판:
四無色定
梵語 catasra ārūpya-samāpattayaḥ。又作四空定、四空處定、四無色。指超離色法（物質）繫縛之四種境界。即由思惟四無色界所得之定。若欲生於此四無色界，則必須修習四無色定；換言之，四無色定，乃對治色法之繫縛，滅除一切對外境之感受與思想的修行，及藉此修行所達到的清淨無染、虛空靜寂之精神境界。此四無色定各有兩類情形，即：生於四無色界之「生無色」，於此之時，定心現前，故得定之名。非由生得，而係修證所得；蓋假令其身雖猶在欲界等下地，然若因修證而現起無色界之定心，則亦得無色之果，稱為「定無色」。
據法蘊足論卷八無色品、大智度論卷十七等載，此四無色定即：空無邊處定，又作空處定。此定超越色界之第四禪，滅除障礙禪定之一切想，思惟「空間為無限大」，亦即思惟空無邊之相。識無邊處定，又作識處定。此定超越空無邊處定，而思惟「識為無限大」，亦即思惟識無邊之相。無所有處定，又作少處定。此定超越識無邊處定，與無所有相應，即思惟無所有之相而安住之。非想非非想處定，又作非有想非無想定。此定超越無所有處定，思惟非想非非想之相，具足而安住之。此定無明勝之想，故異於滅盡定；亦非無想，故亦異於無想定。
四無色定各以其自體而言，皆稱為根本定；接近根本定前之預備階段，稱為近分定，或加行定。加行，即事先加功用行之意。其中，空無邊處定之近分定，係緣欲界第四禪之色相以修行厭離，而尚有色想；然其餘三定之近分定及四定之根本定則全無色想，故四定仍總稱無色定。又非想非非想處定係依定之自相而立名，其下三定則依加行而立名。

mastered the fifth fine-material  object expands the counterpart

expression “base of infinite space,” strictly speaking, refers to the concept of infinite

空無邊處
梵名 Ākāśānantyāyatana，巴利名 Ākāsānañcāyatana。又作阿竭禪天、虛空知天、空知天、空無邊處地、空無邊處天、空處。乃四無色界之第一天，三界九地之一。指厭離形色之身，欣求虛空無邊，由加行入空無邊處定為因，所得定地之果報。由於厭離形色故無色蘊，僅由受、想、行、識之四蘊而成「異熟生」。無色界雖無處所，然有果報之差別，故暫付「處」之名。俱舍論頌疏論本卷八（大四一‧八六四上）：「修此定前，於加行位，厭有色身，思無邊空，作空無邊解，名空無邊處。」

## 비상비비상처정
비상비비상처정은 무소유처정에서 더 나아간, 무소유처정의 마음을 명상 대상으로 하여 집중하는 선정으로, 그 상태가 극히 미세하여 마음이 있다고 할 수도 없고 마음이 없다고 할 수도 없는 선정이다."非想非非想處天", 星雲. 佛光大辭典 3판:
非想非非想處天
非想非非想處，梵名 Naiva-saṃjñānāsaṃjñāyatana，巴利名 Nevasaññānāsaññāyatana。非想非非想乃就此天之禪定而稱之。此天之定心，至極靜妙，已無粗想，故稱非想；尚有細想，故稱非非想。又作非非想天、無思想亦無無想天、有想無想智天、非想非非想天、非有想非無想處天。乃無色界之第四天。此天位於三界九地之頂上，故又稱有頂天。此天之名有三種解說：非如色界四禪及前三無色之明了之想相，故稱非想；非如無想及滅定，故稱非非想。因此地癡闇不明了、不決定，故稱非想非非想。如無色界之第二天，不緣識處，故稱非想；如第三天，不緣無所有，故稱非非想。於無色界第三之無所有處，除識處之想，今又除無想，共捨除想、無想，故稱非想非非想。由上之三說可略見此天之相狀。

This fourth and final immaterial attainment is so called because it cannot be
said either to include perception or to exclude perception. In this type of consciousness,
the factor of perception  has become so subtle that it can no longer perform the
decisive function of perception, and, thus, this state cannot be said to have perception.
Yet perception is not altogether absent but remains in a residual form; thus, it cannot be
said not to have perception. Although perception alone is mentioned, all the other mental
constituents in this
