Based on this view (More reading and researching are better than listening. Non of scholar learns from listening), Buddha is useless because he spoke only but never wrote any book for reading. Preah Sereyboth and Preah Moklean should not be considered as wonderful person since their knowledge was solely from listening the Buddha but not reading as Buddha did not compose a book. As long as you do not honestly concentrate to find the truth in an idea, your dishonesty will lead you to create a new idea to fight back and that new idea will never be accurate. If you are afraid of shame and do not acknowledge the inaccuracy of your idea, you will be fall deeper an deeper into mistake and become an big enemy of the truth. Because of this small issue, being an enormous enemy of the truth will probably remain with you for life because it is the truth which you can not accept.
