Self-deception is such an easy trap to fall into.
Not too many deceptions can survive real tests - how about a tsok of urine and feces? While I don't think we will have any (or many) real Tilopa's this level of testing can bring people back to reality.
As Konchog Norbu notes on FB with a quote from Shechen Gyaltsap:
"Now, by recognizing that appearances are the mind, the mind is empty, emptiness is nondual, and nonduality is self-liberating, one clears away all misconceptions about the outer, inner, secret, and absolute.
"However, this alone is not much help if you have not liberated your own mind into the absolute nature, just as ice, despite being water, does not function as water unless you melt it. So it is important to meditate with intense devotion."
So with the first part we can delude ourselves into believing that we have really actualized wisdom but with the second we can awaken honestly to the truth of our current practice and understanding and non-perfect compassion and get back to work.
Kirt's Tibetan Translation Notes
"Even if you practice only for an hour a day with faith and inspiration, good qualities will steadily increase. Regular practice makes it easy to transform your mind. From seeing only relative truth, you will eventually reach a profound certainty in the meaning of absolute truth."
Kyabje Dilgo Khyentse Rinpoche.
"Only you can make your mind beautiful."
