Many ways. Depends on the disciple. To change his errors. Flaws. The biggest flaw is not knowing he is the divine
From Yogananda he said,
Ignorance is the archenemy of man.
Therefore, to guide yourself and others by wisdom is the greatest wisdom.
To all those who are around me, I speak without weighing my words. If I see error in their ways, I tell them so. But I never try in any way to muffle anyone’s reason.
Obedience to the Guru is the surest way when one is seeking God.
Master [Swami Sri Yukteswar] first told me what to do, and afterwards gave me the reasons. I found him unerring in his wisdom.
By listening to him, I saved myself from many incarnations of roaming and trying to find the truth by myself.
Guru is He who has experienced truth. He serves as a guide in the dark forest of life. If you follow him, he will lead you out of the darkness.
If you try to find the way alone, you may needlessly lose yourself in the forest for many incarnations. So follow the Guru, and he will take you through safely.
Forms and dogma should not control religion. Religion must be based on reason,
and that reason is supplied by the Sankya philosophy.
~Paramahansa Yogananda

So the Guru when he wants obedience, he is not a dictator but they see things about what is to happen and help guide the disciple. They are humble and cannot brag that they know what is to happen. So they softly suggest, what do you think, maybe you should postpone your trip to visit your friend by a day? We insist on going and have an accident.
But conversely when we don’t go, we avoided the accident but don’t know that we gained something by the suggestion
But such Guru are rare!
