All that a Guru can tell you is: “My dear Sir, you are quite mistaken about yourself. You are not the person you think yourself to be.”
Trust nobody, not even yourself. Search, find out, remove and reject every assumption till you reach the living waters and the rock of truth.
Until you are free of the drug, all your religions and sciences, prayers and Yogas are of no use to you, for based on a mistake, they strengthen it.
But if you stay with the idea that you are not the body nor the mind, nor even their witness, but altogether beyond, your mind will grow in clarity, your desires — in purity, your actions — in charity and that inner distillation will take you to another world, a world of truth and fearless love.
Confide in your inner self.
The greatest Guru is your inner self. Truly, he is the supreme teacher.
He alone can take you to your goal and he alone meets you at the end of the road. Confide in him and you need no outer Guru.
But again you must have the strong desire to find him and do nothing that will create obstacles and delays.
And do not waste energy and time on regrets.
