In practice, you have to put down your airs and be prepared for hardship. Work hard and do things in a down-to-earth manner; Calm down and think about it. Practice may be a long historical process. If it is proved that what we are pursuing is wrong through a long process of practice, then we should resolutely abandon it. Practice is a science, and there can be no hypocrisy or reluctance.
