我不认为有极限。

You do not need to leave your room. Remain sitting at your table and listen. Do not even listen, simply wait. Do not even wait, be quite still and solitary. The world will freely offer itself to you to be unmasked, it has no choice, it will roll in ecstasy at your feet.

初心本无善恶，但念头一动，便有了分别心。与其纠结对错，不如回归本心，像孩子一样纯粹地看待世界。
