Questions based on ignorance may not lead to answer that leads to nibbana:
This is how he attends unwisely: ‘Was I in the past? Was I not in the past? What was I in the past? How was I in the past? Having been what, what did I become in the past? Shall I be in the future? Shall I not be in the future? What shall I be in the future? How shall I be in the future? Having been what, what shall I become in the future?’ Or else he is inwardly perplexed about the present thus: ‘Am I? Am I not? What am I? How am I? Where has this being come from? Where will it go?’
He attends wisely: ‘This is suffering’; he attends wisely: ‘This is the origin of suffering’; he attends wisely: ‘This is the cessation of suffering’; he attends wisely: ‘This is the way leading to the cessation of suffering.’ When he attends wisely in this way, three fetters are abandoned in him: personality view, doubt, and adherence to rules and observances. These are called the taints that should be abandoned by seeing. MN2.
