I havent reached Enlightenment and the only person who I met that convinced me that he might have reached it was Adi Da, by his Shaktipat and by my intuiting his divine nature. that is a lot of convincing.
The only other teacher I met briefly was Sri Chinmoy and I didnt get any feeling he was Enlightened.
So If someone cant convince you of his extraordinary nature and power then He is no more likely to have such then the naked emperor is to have clothes assuming you are spiritual enough to recognize spiritual energy.
It is written in the traditions that it is the duty of the disciple to find the true Guru.
My INdian neighbor ,from INdia,in Berkeley once said,All the gurus are fakes.
