My Understanding : When you read good books, your senses and conscience become more energized. As you learn new things, you may feel inspired to implement them, which can make you more responsible, but also lead to stress without realizing it. This stress can cause irritation and anger. However, despite these emotions, your conscience will eventually return to its natural state of comfort. If your conscience becomes attached to either good or bad things, you will have to face the consequences of those attachments.
