注大乘入楞伽經 3.80

3.80

明外道見世間所作法，有已還無，悉是無常。妄計神我為常，待無常已，比知是常。佛則反是，不因此說以為常也。

This explains that the heterodox see that what is produced in the world, having existed, becomes non-existent again, and is entirely impermanent. Falsely imputing a spiritual self (ātman) to be permanent, they await impermanence and infer by comparison that it is permanent. The Buddha is the opposite of this; he does not speak of it as permanent on account of this.
