"It's said,

'When you learn to be a big idiot, then you start to have some skill; Studying until you are as if stupid is the beginning of real insight.'

If you can learn to be as if stupid, then no matter what Dharma door you cultivate you will attain samadhi and gain some realization. It's just because you are unable to be stupid that you cannot properly enter into samadhi and don't get any response from your cultivation."
