亦名純淨識。合論曰。寄說阿陀那識（此云執持）為第九純淨識。如五六七八等識。常依九識以依止。凡愚不了。妄執為我。如水暴流不離水體。諸波浪等。以水為依。故五六七八識。常以淨識為依。何謂九為淨識。為二乘人久在生死業種六七八識有怖畏故。恐彼難信。方便於生死種外。別立淨識。使令悲智漸漸得生達識成智。深密經頌云。阿陀那識甚微細。一切種子如暴流。我於凡愚不開演。恐彼分別執為我。

It is also named the purely clean consciousness. The Helun states: Lodging an explanation, it designates the ādāna consciousness (translated here as 'appropriating and maintaining') as the ninth purely clean consciousness. Just as the five, six, seven, and eight consciousnesses constantly depend on the ninth consciousness as their support, the ordinary and foolish do not understand and deludedly grasp it as a self. Just as a violent torrent of water does not separate from the substance of water, and all the waves rely on water, so the five, six, seven, and eight consciousnesses constantly take the pure consciousness as their support. Why is the ninth called the pure consciousness? Because people of the two vehicles have long harbored fear of the sixth, seventh, and eighth consciousnesses as karmic seeds of saṃsāra, fearing that they would have difficulty believing, as an expedient means, outside the seeds of saṃsāra, a pure consciousness is separately posited, causing compassion and wisdom gradually to arise and leading them to penetrate consciousness to accomplish wisdom. A verse of the Sandhinirmocana Sūtra states: 'The ādāna consciousness is extremely subtle and fine, / All seeds are like a violent torrent; / I do not expound it to the ordinary and foolish, / Fearing they would discriminate and grasp it as a self.'
