My dear , on April 8, 1975 in Mayapur, West Bengal, India Srila Prabhupada very explained as follows on a morning walk:
"So a disciple is always in deficiency before his spiritual master. Just like Caitanya Mahāprabhu says, guru more murkha dekhi karila śāśana [Cc. Ādi 7.71]. 'My spiritual master saw Me a fool number one. Therefore he has chastised Me.' So disciple should be always ready to be chastised. He should not think that he has become perfect. That is perfection. So long he thinks that he is
not perfect--he's to be chastised—then he's perfect. And as soon as he thinks that he has become perfect, he's nonsense immediately, nonsense number one."
Therefore, every disciple should always be ready to be chastised by his or her spiritual master.
