注大乘入楞伽經 1.56

1.56

此明種種勸其離異見。若異見者，則是斷見。謂若異此如實之見，則為斷滅見也。汝應永離心、意、意識，應勤觀察一切諸法者，言自證法，非心意識境界，故當遠離之。勤觀察者，當如理觀察一切法性也。應修內行者，當潛行密用也。莫著外見者，即下所謂二乘、外道句義境界也。圍陀諸見者，即外道婆羅門，遵奉梵天所說四圍陀書，可十萬偈，咸口相傳，不書皮貝。亦不應住六定等中者，即外道異計，欣厭六行伏惑等定也。如一種外道，計第四禪無想一天為涅槃，而於欲界修無想定，厭下三禪及於欲界為苦麁障，欣上無想天是淨妙離，故得下三禪及欲界惑伏而不行。命終即生無想異熟，經五百劫，還即墮落，流轉生死。如是等六行伏惑邪定，皆不應住耳。

This explains various admonitions to abandon deviant views. "If one holds deviant views, these are views of nihilism" means that if one deviates from this view that accords with reality, it becomes the view of nihilistic annihilation. "You should forever abandon mind, intellect, and mental consciousness, and diligently contemplate all phenomena": this means that the internally realized Dharma is not the cognitive sphere of mind, intellect, and mental consciousness; therefore one should abandon them. "Diligently contemplate" means that one should contemplate the nature of all phenomena according to principle. "You should cultivate internal practices" means that one should practice secretly and function subtly. "Do not cling to external views" refers to the realms of words and meanings belonging to the two vehicles and heterodox paths, as explained below. "The views of the Vedas": these are the non-Buddhist Brahmins who revere and uphold the four Vedas spoken by Brahmā, consisting of roughly one hundred thousand verses, all transmitted orally and not written on leaves or bark. "Nor should you abide in the six dhyānas and the like": these are the deviant tenets of heterodox paths, namely samādhis of the six practices of disgust and delight that suppress defilements. For instance, one type of non-Buddhist considers the single Non-Conception Heaven of the fourth dhyāna to be nirvāṇa, and in the desire realm cultivates the non-conception concentration; detesting the lower three dhyānas and the desire realm as painful, coarse, and obstructive, and delighting in the higher Non-Conception Heaven as pure, wonderful, and detached, they cause defilements of the lower three dhyānas and the desire realm to be suppressed and not arise. When life ends, they are reborn in the non-conception ripening, and after five hundred eons, they immediately fall again and wander in saṃsāra. One should not abide in any such heterodox concentrations of the six practices for suppressing defilements.
