"Paltrul's 'Self-Liberated Mind':
"'At times it happens that some meditators say that it is difficult to recognize the nature of the mind (note: in Dzogchen, 'the nature of the mind' means the ultimate reality of pure Emptiness or primordial Spirit). Some practitioners believe it to be impossible to recognize Spirit. They become depressed with tears streaming down their cheeks. There is no reason at all to become sad. It is not at all impossible to recognize. Rest directly in that which thinks that it is impossible to recognize Spirit , and that is exactly it .'"
