To him, the Guru is Guru even if he acts unconventionally. Always remember that the nature of a saint is unfathomable. Judge him not. Measure not his divine nature with the inadequate yardstick of your ignorance. Criticise not your Guru's action which is done on universal vision.
True discipleship opens the vision.
It kindles the spiritual fire. It awakens the dormant faculties. It is most necessary in one's journey along the spiritual path. Guru and disciple become one. The Guru blesses, guides, and inspires the disciple.
