Pray sincerely from within, “O kind and compassionate Guru, please take me to the other shore.” There is nothing to fear.
Never have fear! Even if you have fallen, it does not matter. The guru preceptor is the rescuer of the downtrodden.
Don't differentiate between guru and god.
In order to achieve samadhi (realization), have strong self-control in every aspect, practice steadiness of mind, put your faith in the scriptures and your guru, accompany this with devotion, compassion for others, and remain non-attached.
The moment you come to the path, the guru preceptor has accepted you as his own.
The guru preceptor is present in all forms. All sadhanas are the form of the guru. But even if someone is leading you down the wrong path, then that is something quite different. [If a sadhu is misguiding, he is not the form of the guru].
Even if you have achieved a highly advanced state, there are still obstacles on the path you must overcome. This is why one should maintain faith in the guru preceptor.
