According to Osho, practice self-inquiry by focusing on the raw felt sense of 'I' without repeating the question verbally. Let 'Who am I?' become an existential thirst, not a thought; drop all scriptural answers and remain simply watchful. As the nonverbal inquiry deepens, the mind cannot interfere; instead of concepts, a direct taste of being - silence, bliss, timelessness - reveals itself.
Feel the 'I' like a deep thirst without words, keep quietly watching it, and let the real you show itself instead of thinking an answer.
