This is moha. The first mind is moha, and the second and third mind are also moha.
Delusion works this way. The first mind thinks what it wants to think; it makes an assumption. The second mind believes this mind, and the third mind exaggerates the belief. But if awareness is present, delusion either stops or cannot grow.
(Elsewhere: So, if a thought agitates the mind and makes the mind suffer, don’t believe the thought and also don’t follow the thought.)
