A quote by Nisargadatta Maharaj (April 17, 1897 – September 8, 1981).
Rajneesh [Osho] is not a small personality or small principal. He is tremendous ‒ he is very big. He is a great sage.
When you already have a guru [Rajneesh], why do you visit other sages? Since you already have a great sage as your guru, you should not sit here or come here. I do not like those shiftings from gurus to gurus. I do not like wanderers. What is the difference between Maharaj and Rajneesh [Osho]? Once you remove the letters (that is, the names) what is the difference? You investigate that wanderer’s ‘I’, before you investigate others. What is the product after you remove its name? What are you without the name or the label?
You investigate the investigator – investigate ‘I Am’.
