大乘起信論裂網疏 6.35

6.35

此先揀所觀之境也。不依氣息者，謂一切氣息來無所從，去無所至，當體不可得故，故不依此以修阿那般那三昧，以阿那般那不可得故，即是摩訶衍也。不依形色者，謂一切形色，分析乃至微塵，皆無所有，故不依此以修九想、十想、八背捨等諸定，以九想乃至八背捨皆不可得故，皆即摩訶衍也。不依虛空者，謂對色名空，色尚非有，云何有空？故不依此以修空一切處三昧，以空三昧不可得故，即是摩訶衍也。不依地水火風者，謂推析地無堅性、水無濕性、火無熱性、風無動性，當體不可得故，故不依此以修勝處、一切處等三昧，以勝處、一切處等不可得故，即是摩訶衍也。乃至不依見聞覺知者，謂由色聲香味觸法境界，說有見聞覺知，今推所見、所聞等並非實有，則能見、能聞等安得有實，故不依此以修識一切處三昧，以識三昧不可得故，即是摩訶衍也。

This first eliminates the objects contemplated. 'Does not rely on breath' means that all breathing comes from nowhere and goes nowhere, its very substance being ungraspable; therefore one does not rely on this to cultivate ānāpāna samādhi, because ānāpāna is ungraspable, which is itself Mahāyāna. 'Does not rely on physical form' means that all physical forms, when analyzed down to subtle dust, are non-existent; therefore one does not rely on this to cultivate the samādhis of the nine notions, ten notions, eight liberations, and so forth, because the nine notions up to the eight liberations are ungraspable, which are all themselves Mahāyāna. 'Does not rely on space' means that space is named in contrast to form, and since form does not even exist, how could there be space? Therefore one does not rely on this to cultivate the samādhi of the base of all-space, because the space samādhi is ungraspable, which is itself Mahāyāna. 'Does not rely on earth, water, fire, or wind' means that when analyzed, earth has no solidity-nature, water has no wetness-nature, fire has no heat-nature, and wind has no movement-nature, their very substance being ungraspable; therefore one does not rely on this to cultivate the samādhis of the bases of mastery, totality, and so forth, because the bases of mastery and totality are ungraspable, which are themselves Mahāyāna. 'Even does not rely on seeing, hearing, perceiving, or knowing' means that seeing, hearing, perceiving, and knowing are spoken of based on the spheres of forms, sounds, odors, tastes, tangibles, and dharmas; now, investigating that the seen, heard, and so forth are not real existents, how could the seer, hearer, and so forth be real? Therefore one does not rely on this to cultivate the samādhi of the base of all-consciousness, because the consciousness samādhi is ungraspable, which is itself Mahāyāna.
