The author of Caitanya-caritamrta, he is presenting himself: purisera kita haite muni sei laghistha [Cc. Adi 5.205]: "I am lower than the worm of the stool." Purisera kita haite muni sei laghistha. Laghistha means lower, lowest. Jagai madhai haite muni sei papistha. Jagai and Madhai was taken, they were drunkards, woman hunters; therefore they were sinful. So Caitanya-caritamrta kar says that jagai madhai haite muni sei papistha. Although… This is the way. Nobody think himself as one has become very big man and he has his own opinion to give. This is rascaldom. So everyone should think that "I am… What is my value?" That is really learned: humble and meek. Nobody should think that "Now I have learned everything. I can surpass everyone. I have become above all rules and regulation. Now I have become paramahamsa." This is rascaldom. Everyone should always think, "I am fool number one." Therefore the endeavor will go on, to become perfect. If we think that "Now I have become perfect, paramahamsa," then the spiritual regulative principles will never be followed, and you will fall down.
