According to Dzogchen, and the special approach of the great Dzogchen master Shri Singha, there is a way of recognizing the nature of mind solely through devotion.
There are cases of practitioners who simply through their heartfelt devotion attained realization, even though their teacher had already passed away or was nowhere near them physically.
Because of their prayers and devotion, the nature of mind was introduced. The classic example is that of Jigme Lingpa and his consuming devotion for Longchen Rabjam.
