Ignorance can be removed only through Self-Enquiry. This is the first stage. Only when we totally accept that we are ignorant can we remove ignorance. When we accept from our very core that we are absolutely useless, with all humility, will the next door towards Truth open up. Then when one searches, Nature opens new doors towards Guru. When we meet our Guru, that indicates the second step. With the guidance of Guru, we begin sadhana and start enquiring deeper into the deep processes of life. This shall remove the major layers of ignorance. This was the third step. At the final stage, we have to surrender completely through the Guru to the one who is the source of everything, Bhagawan. This is the penultimate stage. Then till the stage of God-realization, it is on auto mode. This is the fifth and the last stage.
