26.61

他心智唯四者，他心唯依四靜慮，起五通所依止觀等故，由此餘地無他心智。

"The knowledge of others' minds is on only four": the knowledge of others' minds relies solely on the four dhyānas, because the calm abiding and special insight upon which the five supernormal knowledges arise are in equilibrium there; for this reason, it does not exist on the other levels.
