大乘起信論裂網疏 6.69

From here down, it clarifies all the marks of faults arising from seeing demonic shapes and hearing demonic sounds; now it first clarifies the marks of simulated roots of goodness. However, this practitioner of calming aims solely to quell beginningless ignorance and realize untainted wisdom; they should not seek after the five superknowledges and the four unhindered eloquences. Now, before attaining the untainted state, they first obtain knowledge of past lives, the minds of others, eloquence, and so forth, so they will inevitably fall into the pit of fame and profit. Just as Devadatta cultivated and attained the five superknowledges and subsequently committed the three deadly sins, this serves as an instructive warning.
