大乘起信論裂網疏 6.66

6.66

Here, it sequentially distinguishes the demonic sounds spoken by fake Buddhas, bodhisattvas, and so forth. A person properly cultivating samādhi does not rely on breath, does not rely on visible forms, and so forth, even discarding thought. One should know that they also do not rely on dhāraṇīs, do not rely on the perfections, do not rely on the gates of liberation, and even do not rely on the original nature being nirvāṇa. As soon as one relies on the original nature being nirvāṇa, one will inevitably reject cause and effect, falsely reckoning a realm of non-existence prior to the empty kalpa or on the other side of Bhīṣmagarjitasvararāja to be the tathatā samādhi. How could this be what is meant by 'if one knows that the stirred mind is just non-arising and non-ceasing, one then enters into tathatā'? The first part, distinguishing shapes and sounds, is finished.
