注大乘入楞伽經 6.167

6.167

言二乘厭生死求涅槃，計有五陰等諸法，不達唯心量。佛智清淨，知陰界處相不實，名達心量。

This means that the two vehicles abhor saṃsāra and seek nirvāṇa, conceiving that all dharmas such as the five aggregates exist, and do not thoroughly realize that it is cittamatra. The Buddha's wisdom is pure; knowing that the characteristics of aggregates, realms, and sense-bases are unreal is termed thoroughly realizing cittamatra.
