2.107

故知不變則色心諸法俱真，隨緣則色心諸法俱妄。於俱妄中心是能造故，多令觀心；心法近要故，多令觀心；為破下界著色重故，多令觀心，實非心獨是理故令觀心。若知此意，即不執說真理便為觀心。

Therefore we know that in unchangingness, all phenomena of form and mind are all true; in following conditions, all phenomena of form and mind are all deluded. Amid what are all deluded, because the mind is the creator, one is largely directed to contemplate the mind; because the mental factor is proximate and essential, one is largely directed to contemplate the mind; to break the heavy attachment to form in the lower realms, one is largely directed to contemplate the mind. It is truly not because the mind alone is principle that one is directed to contemplate the mind. If one understands this intention, one will not stubbornly hold that speaking of the true principle is itself contemplating the mind.
