According to Osho, the title 'Acharya' has no spiritual significance; it was merely a regional academic designation for a professor that stuck to his name. Because it breeds confusion and reinforces concern for others' perceptions, it should be dropped. Spiritual identity, he says, lies in authentic, blissful living, not in titles, clothes, or borrowed images.
It's just an old job title, not a holy label; who you are has nothing to do with names or outfits.
